Insects surround us! They are big and small -- from showy swallowtails and darner dragonflies to minute parasitoids​ and leaf litter critters. Some insects are colorful and charismatic, and others are drab and obscure.

Insects are broadly subdivided into orders. The five largest orders include: Hymenoptera (sawflies, ants, bees, & wasps), Coleoptera (beetles), Lepidoptera (moths & butterflies), Diptera (flies, gnats, mosquitoes), and Hemiptera (stink bugs, aphids, cicadas, etc.). At Cornell, you can find representatives of 24 out of the 28 orders of insects!
Not only is there a diversity of insect species, families, and orders that can be found on campus, but at Cornell we also have a huge collection of museum specimens from around the globe. The Cornell University Insect Collection (CUIC) houses over 7 million specimens which are available to researchers worldwide. Cornell undergraduate students are active participants in the curation of the CUIC specimens. ​Some of the insects collected by the students in our course will be maintained for future scientific studies.
Header photo: winter stonefly (order Plecoptera, family Capniidae).
​This adult insect is about a quarter of an inch long and can be found walking on the snow! Stoneflies are a sign of a healthy stream. At Cornell, a winter stonefly may be encountered near Fall Creek or Cascadilla Creek. Look for them in late January into February while on your walk around campus.
