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!

Must Have Equipment for Entomology

Blog, She Wrote: Must Have Equipment for EntomologyIf you are going to collect insects, then you’ll need the right equipment. Today’s post is a list by category of the Must Have Equipment for Entomology.

Be sure to buy equipment that is meant for serious entomologists and not items that are essentially toys. We bought an Insect Collectors Backpack Kit from Home Science Tools for his birthday. While this was not everything Joshua needed once he got serious, it was a great starter kit and we only needed to supplement our initial investment.

Our other supplier is BioQuip Products which specializes in equipment, supplies, and books for entomology and related sciences.

Materials for Collecting

  • Aerial Net- For sweeping over vegetation and collecting terrestrial insects
  • Aquatic Net- A seining type of net for use in the water to collect aquatic species of insects.
  • Flat Pans- For pouring water collections into
  • Flat Tweezers on a String- for catching the aquatic species from the pan
  • Killing jar- jar of any kind with tissues inside. The jar usually has a substrate on the bottom to hold the ethyl alcohol when you pour it in. The out-gassing of the ethanol into the jar will kill the insect.
  • Aquatics Jar- filled with isopropyl alchol to keep aquatic and soft-bodied insects when you collect them.

Supplies for Pinning & Spreading

  • Quilting Pins- to hold the legs, wings, & other appendages into place while the insect is drying
  • Insect Pins- in various sizes from 0 to 3. For use with different sized insects
  • Tweezers/Forceps- for handling the insects precisely
  • Magnifying Lens- to see the insect features up close
  • Glassine Envelopes- These are also used in collection (which we’ll talk about tomorrow). They are for temporary storage of moths & butterflies so you don’t destroy their wing scales, but they are also useful in holding wings in place during drying.
  • Scissors- for cutting apart the glycene envelope when you pin insect wings
  • Small Ruler- so you can measure where the insect is on your pin.
  • Spreading Board- made so you can place the body of the insect in the groove and coax the wings out very carefully. Joshua made his own out of insulating foam block and dowels.
  • Pinning Block- this foam can’t easily break and is thick enough to pin insects which don’t need any wing spreading.
  • Paper Points- for displaying tiny insects rather than pinning them through
  • Elmer’s Glue- for the occasion when a leg falls off. Elmer’s to the rescue! This is also how we get an insect to display on a point.

Equipment for Handling Aquatic Species

Listed here are items you’ll need for handling aquatic insects and soft bodies insects such as caterpillars.

  • Jar- for collecting day
  • Isopropyl Alcohol- For preserving the insect. How to use it will be in tomorrow’s post!
  • Small Glass Vials- in a few small sizes depending on the size of your specimen
  • Screw Cap Collecting Tubes- These allow you to collect aquatic insects which are larger and hold specimens for putting them into their display vials.

Blog, She Wrote: Must Have Equipment for Entomology

Materials for Displaying Your Insect Collection

One of the requirements in our entomology club is to share your collection in a public display. On Wednesday afternoon, Joshua will turn in his collection and he’ll talk to a judge about his experience. Then his collection will go on display at the fair for the rest of the week.

  • Case with a Glass Lid- So that people can see your insect collection without taking the glass off. The backpack kit we got came with a small box.
  • Pins for Labels- For holding the labels
  • Laser Printed Labels- So that the labels don’t smear when you place them in the vials with alcohol
  • Vials- the small glass variety in various sizes

We ordered about $40.00 worth of equipment from BioQuip, Inc outside of the Backpack Kit from Home Science Tools. We use items from the kit as well including the field guide. Next season, which starts in September, we’ll be ordering a few more supplies to add to our collection of equipment.

You want to be well-equipped to do the job right. There is so much to learn and inferior materials will make the work more difficult.

Tomorrow I’ll be sharing all about where and how to collect your insect specimens.

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.

Blog, She Wrote: Entomology- The Science of Insects

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!
