Labeling Your Insect Collection

As you might have predicted, there are rules on how to label an insect collection for display. Here are a few key points:

  • Number Labels- Each insect in the collection gets a number. If it is a 4-H collection, a numbered insect must have been collected in the current fair year (not before the previous year’s fair). You can have those insects in a collection, but they cannot be numbered in that year’s collection. These labels are the last ones on the pin with the insect.
  • Collection Labels- The first label on the insect pin (underneath the insect) is the collection information. Where the insect was collected and when along with the name of the collector.
  • Identification Label- For 2nd year collections and up, you must include another label which goes between the number and collection information. It will have the family name of the insect as well as the genus and species. Correctly identifying the insect to the species is important for point value.
  • Order Labels- These are larger labels and they are pinned inside the box. When you organize your collection do so by order.
  • Common Name Labels- Required after the first year, these labels tell the common name of the insect and usually include a family name (so not just “fly” but “crane fly”)

Keeping a Collection Record

Along with all the labeling in the box, you must turn in a collection record. Since the collections are additive over the years, these records can be many pages long. Below are listed the information you need to keep:

  • Insect Number- comes after you’ve labeled your insects
  • Common Name- 2nd year and beyond
  • Order
  • Family
  • Genus Species
  • Locality- location of collection
  • Date Collected
  • Place Collected- what habitat

A first year collection only needs to be identified to the order. After that, more work is required!

Other Tips for Insect Displays

In addition to the labeling, here are a few more helpful hints:

  • Group orders of insects together in the collection and place the order label nearby
  • Numbers within an order should be chronological
  • Place the vials toward the bottom of your collection- So if they come loose, they don’t wreck other insects in the box!
  • Keep a collection record as you go- This is a time saver when you are preparing your collection for evaluation!

For more information on making displays, check out How to Make an Awesome Insect Collection from Purdue which follows 4-H guidelines for entomology projects.

This has been an exciting project area for us this year. We’ve already started next year’s collection. As of publishing time for this post, the collection pictured here has won a blue ribbon and a project excellence for first year collections and is headed for the NY State Fair next month.

Enjoy the collecting!

Best Practices in Pinning Your Insects

Blog, She Wrote: Best Practices in Pinning Your Insects

Once you have insects stored, you are ready to pin! Today I’ll be sharing how to properly pin an insect.

Pinning the First Pin through the Body

It’s probably no surprise that there are rules that go with pinning insects. How to Make an Awesome Insect Collection from Purdue University quite nicely outlines the information on how to pin. I’ll try to pick out some highlights for you here.

  • Each insect that is big enough to be pinned through the body without breaking will get a pin directly through the body- usually to the right side and between the first and second appendages on the thorax. The pinning location does vary by insect order though so you need to read the rules!
  • The size of the pin (0, 1, 2, 3) is dependent on the size of the insect you are pinning. Smaller insects use smaller pins and vice versa.
  • You want to be sure that the insect on the pin is not tilted- either side to side or up and down. It needs to be straight on the pin.
  • If your insect does not have wings or it is not typical to spread the wings of this particular insect, then you can pin the legs and antennae into position while the insect dries. That’s when quilting pins are useful.

Spreading Insect Wings

An insect with its wings spread out can look fantastic in a collection. It’s a careful job to be sure! You can check out this advice on spreading wings, but here are a few more tips.

  • Place the winged pinned insect on the spreading board in the valley. You may have to adjust the width of the board to accommodate large insects.
  • Use a size zero pin to gently pull the wing along the surface of the spreading board. When you get it to where you want it, use a slice of glassine envelope with the quilting pins to hold it into place. You want to be very purposeful with this motion.
  • Once you have the first pin in place, then you can add more as you see below.
  • As the insect dries, you can leave the coverings in place to protect the wing- especially those wings with scales as in butterflies and moths.

Blog, She Wrote: Best Practices in Pinning Your Insects

Once your insects are pinned, you need to let them dry for a few weeks before placing them into a case. You want to be sure they dry to avoid odors and you have to keep the whole thing dry to make sure nothing like mold grows on your specimens or that it doesn’t attract parasites which can eat the insect from the inside out.  Yes, that is as gross as it sounds.

The last post in this series is all about the finished display of insects and preparing it with official entomological guidelines.

Best Practices for Collecting Insects

Blog, She Wrote: Best Practices for Collecting Insects

Now that we know what entomology is and how to identify insects, and we have all of the equipment we need to get started, it’s time to collect our insects! Today is all about Best Practices for Collecting Insects- how to collect and preserve all sorts of insects.

Collecting Terrestrial Insects

You can find specimens flying through the air or crawling on the ground. How do you catch the insects- especially the dangerous ones?

  • Use an Aerial Net- To catch insects which fly, take an aerial net and “sweep” it over tall grasses in a meadow. It’s best to do this in the heat of the day when the flying insects are most active.
  • Clasp the Net- So that the insects which have gone in have to stay and usually you can work them to the opening you create while you have the killing jar at the ready.
  • Use Your Killing Jar- Make sure your jar is “charged” with ethyl alcohol and open it. Around here, it’s a two person job. One has the net and the other is ready with the jar. You can even do this with bees and yellow jackets, but you must be right there with the jar. This is my new go to in the house- rather than swatting, I arm myself with a container!
  • Use any jar or container- Once you have the insect inside, take the container to the freezer. This is a great idea when your killing jar isn’t charged and you aren’t in the field.
  • Be ready with a glassine envelope- Moths and butterflies either need to be paralyzed (which we really haven’t gotten the hang of yet, but requires you to hold it between the wings and squeeze enough to paralyze but not squish) or they can be placed in an envelope and taken directly to the freezer. The trick with these guys is not allowing them to struggle. Once they flap their wings too hard, they will lose scales and it won’t show as well once it’s pinned.

Collecting Aquatic & Soft Bodied Insects

Soft bodies insects are those without an exoskeleton like caterpillars, thrips, silverfish, etc. Aquatic species are larval forms of mayflies, caddisflies, stoneflies, etc.

Both are different from terrestrial species because they get collected and stored in alcohol.

  • Jar of Isopropyl alcohol- Bring along a jar (just a normal kitchen variety) 2/3 full of 70% rubbing alcohol. When it’s time to catch and collect these insects, you just grab them with some forceps and drop them into the jar.
  • Use a pan- To dump the water and critters from the bottom of the creek. From here you and your kids can investigate what came up with the aquatic net for collection.
  • Bring along collecting tubes- Sometimes it’s easier just to bring a few collecting tubes rather than a whole jar of alcohol. They are lighter and easier to carry if you are in a pinch.

Storing Collected Insects

Once you have the insects in your killing jar and alcohol jar, you have to take of them once you arrive home. It’s important to pin the terrestrial insects before long so they don’t dry out on you. Pinning a dried out insect is difficult and leads to breakage.

  • Remove insects from the killing jar- and put them into individual air tight storage in your freezer.
  • Decant the aquatic/soft bodied insects- Pour out most of the alcohol and add new alcohol to the jar. Once the insects die in the alcohol, the water inside of them will diffuse out and dilute the alcohol. You want to avoid that for long because a diluted solution will not preserve the insect. I like to decant and add 90% isopropyl. Decant the solution twice to be safe.
  • Separate the insects into vials- Ultimately, they will need to be in their own container. This will save you time when it comes to preparing your collection for evaluation.
  • Keep them in glass- as opposed to plastic for long term storage so they don’t dry out.

Keeping a Record of Your Collected Insects

You’ll want accurate records of your insect collection as you go along. If you are turning in your collection for judging, a written record is required. Also, you’ll need the collection information on all those tiny labels that go under the pinned specimen. Keeping the information as you go, will save time in the end. Even if you think your collection isn’t large. Here is a sampling of the information to keep:

  • Location of collection- both the place (address, name, and town with county) and the exact habitat it was collection from (pond, meadow, etc)
  • Date Collected- Month, day, and year for each specimen
  • Name of the Collector- You are permitted to have others collect for you, but make sure you note who it is.
  • Name of the Insect- First year entomologists are required to ID to the order only. In the second year, they add common names to the record keeping.

Most of all have FUN! Collecting insects is a challenge which can be very entertaining in its pursuit. As you gather specimens, things get exciting as you find new varieties and add things to your collection. The next step is pinning your insects. Join me!

Entomology- The Science of Insects

Blog, She Wrote: Entomology- The Science of Insects

This summer’s Hopscotch topic here at Blog, She Wrote is entomology. If you are an Instagram or Facebook follower of mine, then you may know that our nine year old is an entomologist. I thought it would be fun for me to report on how his year has gone and to share what we learned with you all.

As I write this, we are preparing for the 4-H Fair and his first year collection is just about ready. We have some labeling to do, but all of his specimens are pinned and we are in the home stretch. Today’s post is all about entomology- the science of insects including classification, & identification.

What is Entomology?

Officially speaking, entomology is:

A branch of zoology dealing with the scientific study of insects, including their taxonomy, morphology, physiology, and ecology.

This year Joshua has been studying entomology by attending lectures every month given by a husband-wife pair of PhD entomologists. They’ve been teamed up for years to lead an entomology project area for 4-H. For most of the time, he’s been attending with another 8 turning 9 year old boy and his dad. That’s right, parents are requested to be there for the ride. He’s had an amazing year learning all the intricate details of insect morphology while learning how to collect and pin insects for his own collection properly.

Blog, She Wrote: Entomology- The Science of Insects

Classification of Insects

Insects are animals with six legs and an exoskeleton- among other common characteristics. They can be divided into many different orders. Even a young entomologist knows his insect orders! As you learn the orders, try to keep up with the latest research because sometimes they change. Our group is working with the latest findings from earlier this year. When entomologists discover orders are so related to each other they don’t need to be separate orders, they are combined. For example, termites and cockroaches are closely related and are no longer separate orders. This will be important if you are taking your insect collection to the fair!

Orders of Insects (as of February, 2014):

  • Archaeognatha- Bristletails
  • Thysanura- Silverfish, Firebrats
  • Ephemeroptera- Mayflies
  • Odonata- dragonflies & damselflies (each in their own suborders)
  • Plecoptera- Stoneflies
  • Notoptera- ice crawlers, rock crawlers, heel walkers (discovered in 2002)
  • Dermaptera- Earwigs
  • Embioptera- Webspinners
  • Phasmatodea- Walking sticks, timemas
  • Orthoptera- Grasshoppers, crickets, katydids
  • Mantodea- Mantises
  • Blattodea- Cockroaches and termites (formerly Isoptera)
  • Zoraptera- Angel insects
  • Hemiptera- True bugs, moss bugs, cicadas, hoppers, aphids (in suborders)
  • Thysanoptera- Thrips
  • Psocoptera- Psocids (booklice & barklice)
  • Phthiraptera- Lice
  • Coleoptera- Beetles
  • Strepsiptera- Twisted winged parasites
  • Neuroptera- Lacewings, antlions, mantidflies, owlflies
  • Raphidioptera- Snakeflies
  • Megaloptera- Alderflies, dobsonflies, fishflies
  • Hymenoptera- sawflies, horntails, wasps, ants, bees
  • Trichoptera- Caddisflies
  • Lepidoptera- Butterflies & Moths
  • Mecoptera- Scorpionflies, hangingflies
  • Siphonaptera- Fleas (though it turns out that fleas are highly developed scorpionflies so this order may soon be reclassified as Mecoptera)
  • Diptera- Flies

Joshua has to have 20 insect specimens with 12 orders represented in his first year collection. I’ve bolded the orders he’s collected this year.

Identification of Insects

Identifying insects comes after understanding insect morphology (form & structure). Once you know about biting mouth parts vs sucking mouth parts and whether to look for wings or not, etc.,  it’s easier to narrow down what the insect is.

Keys help you to look at the insect closely and make decisions based on the characteristics of the species. Use this dichotomous key to identify an insect down to its order.

Joshua has been memorizing the insect orders and trying to remember their features. If the name has “optera” in it, then it’s a flying insect, for example. He’s getting good at identifying by sight, but he still benefits from using the dichotomous key.

Resources for Classification & Identification of Insects

When we meet as a club, the leaders bring their guides to share with us. We also have our field guides. A comprehensive guide is important to an entomologist. Unless you have very young children, I would recommend skipping the children’s guides. I find my kids outgrow them very quickly. They can be less intimidating, but they lack information and sometimes make it hard to identify a specimen.

  • National Audubon Society Field Guide to Insects & Spiders (North American)- This is our main field guide. Not only does it have plenty of information on various species, but the color photographs make it easy to compare in the field- or at pinning time.
  • A Guide to Common Freshwater Invertebrates of North America- This one was useful to us as he identified all of the aquatic species in his collection. Can you tell the difference between different species of mayflies? This book will help! Joshua has at least two in his collection this year.
  • Dichotomous Key- Going beyond matching pictures is sometimes necessary for identification, especially in the insect world. A dichotomous key has students analyze features of the insect and make a choice between one presentation of a characteristic and another. By process of elimination, you come to the final choice which will tell you what the critter is.

One of my favorite things about this entomology club is the way they choose to instruct the kids. Rather than watering down the information, our mentors lecture on the information as if their audience is much older. The wonderful thing is to watch the boys ask for more after an hour of listening intently as anatomy is drawn on the board. I love that it is real science- not classroom oriented, mini-demonstrations or labs.

Knowing your student and providing him with the materials he needs to grow is crucial to seeing your kids stick with a project area and gain experience.

The rest of this series will be about the equipment, collecting, pinning, and displaying an insect collection. Please join in!

High Seas Adventure with The True Confessions of Charlotte Doyle

Blog, She Wrote: High Seas Adventure with The True Confessions of Charlotte DoyleThis post may contain affiliate links. Thanks for your support.

Summer time is a wonderful time for adventure even the kind we experience in books. Join me for some High Seas Adventure with The True Confessions of Charlotte Doyle.

Sailing Resources for The True Confessions of Charlotte Doyle

The setting for this story is a two masted sailing ship called a brig as she sails on the open sea. Any nautical tale is full of unfamiliar terms and responsibilities. Half the fun of this book is deciphering the sailor code. Here a few ideas for a sailing adventure activity:

  • Learn How to Make Knots- We’ve done a lot of knot making in our homeschool. Not only did sailors need to know many knots for various functions, but we use them a lot in camping.  There are lots of online instruction sites including You Tube along with a Klutz Book of Knots (if you can get your hands on one). Other sources for knots are the Dangerous Book for Boys and a game called Knot So Fast by ThinkFun.
  • Repair the Sails- Have you ever repaired anything you’ve ripped? Have you ever hand sewn canvas? Try using a needle and thread to fix a whole in your pants or hand sew a bag using a thick fabric. Is it easy? Can you imagine making everything this way and mending a ship’s sails like the crew members did?

Learn More about Sailing in The Early 1800s

Doing the research on the context of our novel might shed some light on how the characters behaved.

  • Etiquette- What was expected of people in various classes of the time? How was Charlotte expected to behave? How did etiquette contribute to how she treated the crew and what they initially thought of her? This book is just as much about character and the interpersonal relationships between people as it is is about sailing and the voyage. How did etiquette play a part in the plot?
  • Famous Ship Captains, ships, and ports- along with popular sailing routes. You can learn a lot about a time when you read about the people of the time. What was it like to cross the Atlantic in the early 19th century?

As you may have guessed, this topic is a favorite at our house. We’ve got some fun units and activities for you.

Other Sailing Adventure Books

If your kids like stories of adventure at sea, check out these other titles.

  • Swallows & Amazons- This is a series of books based on a group of kids who sail the lake district of England and have adventures there as well as the open water of the ocean.
  • Carry On, Mr. Bowditch- A classic tale of a man who taught himself and learned navigation. You’ll learn a lot about what sailing was like and how the first book of American navigation came to be.
  • Treasure Island- Robert Louis Stevenson’s story of pirates and treasure has plenty of time at sea.
  • Under Drake’s Flag: A Story of the Spanish Main- Any story about early explorers will have an emphasis on their ships and journeys.

The story True Confessions of Charlotte Doyle is a tale of adventure on the high seas- of a girl from the upper crust of society who learns some valuable lessons about life and about who she is. It’s filled with adventure and intrigue and gives us a glimpse of what life was like on a large shipping vessel in 1832.
