Invertebrates

bumble bee

The vast majority of Vermont’s animals are invertebrates—animals without backbones. The Vermont Natural Heritage Inventory tracks site-specific information on 221 rare or uncommon invertebrate species.

Invertebrates include a wide variety of animals. In Vermont, better-known invertebrate groups include:

  • arthropods (insects, spiders, crustaceans, and their kin)
  • mollusks
  • sponges
  • various types of worms

While precisely how many kinds of invertebrates are in Vermont is unknown, it has been estimated at approximately 21,400 species.

The department’s zoologist conducts surveys and works with partners—professional and amateur naturalists alike—to better understand the invertebrates of Vermont.

In Vermont, distribution data and, to varying extents, life history and conservation needs have been fairly well-documented for:damselfly, mussel, butterfly, tiger beetle, and bumble bee

Butterfly Survey – From 2002 to 2007, volunteers searched throughout the state to survey Vermont’s butterflies.

Giant Silkmoth Atlas – From 2002 to 2007, volunteers helped document the status of four of the largest moth species in the Vermont.

Vermont Bumble Bee Survey – From 2012 to 2014, Vermont Center for Ecostudies biologists and citizen scientists spread across the state to survey bumble bees, and the similar appearing, Eastern Carpenter Bee. Nearly half of these bees are of conservation concern.
