Who are the insects and many other life forms who live in our towns?
What do they look like? What are their lifecycles, how do they raise their families, what do they eat, where do they sleep?
Join us as we enjoy the many benefits of nature connection, and increase our knowledge about the natural world and biodiversity, particularly 'nearby nature' in your home locality.

The Eight Major Orders of Insects
There are 26 orders of insects, but the vast majority belong to only these eight. Below is a short guide to the identification of the eight major orders.
Beetles Coleoptera (“sheath wings”)
- largest order of living things with over 290,000 species known worldwide
- two pairs of wings, but the outer pair is hardened covering the top of the body and
meeting in a straight line down the back.
- have “chewing jaws”
- metamorphosis is complete
Moths, Butterflies Lepidoptera (“scaly wings”)
- second largest order of insects (beetles are #1) - mostly moths
- two pairs of wings covered with small scales that rub off easily
- only insects with sucking mouth parts in the form of a coiled tube.
- in the larval stage, most butterfly and moth species feed on leaves, often of a
particular plant or related group of plants
- metamorphosis is complete
Bees, Wasps, Ants Hymenoptera (“membrane-winged”)
- third largest order.
- have 2 pairs of thin, clear, membraneous wings.
- females have a well-developed egg-laying organ and/or stinger at the end of their
abdomen
- ants have wings only at certain stages of life, some have stingers, too
- considered the most highly evolved order of insects.
- Most wasps are parasites; their young hatch and develop inside the bodies of other
insects or spiders. These parasites are our chief ally in the control of many pest
insects.
- Bees and wasps are important pollinators of food crops and other plants.
- metamorphosis is complete
Flies, Mosquitoes, Gnats Diptera (“two wings”)
- fourth largest order (third in North America)
- if an insect has just one pair of wings, it is a fly of some kind.
- all adult flies have sucking mouth parts
- metamorphosis is complete
Crickets, Grasshoppers, Locusts Orthoptera (“straight wings”)
- thin, leathery forewings that cover larger hind wings that are folded like a fan when
at rest.
- important food for birds and other insect eaters.
- metamorphosis is gradual
Dragonflies, Damselflies Odonata (“tooth”)
- 2 pairs of long, narrow, membranous wings that are roughly equal in size.
- they also have large eyes and extremely long, narrow abdomens.
- at rest, dragonflies hold wings out flat, while damselflies hold wings together above
their bodies.
- adults feed on other insects (gnats, mosquitoes)
- metamorphosis is gradual
Aphids, Cicadas, Leafhoppers Homoptera (“same wings”)
- 2 pairs of membranous wings held in a tent-like or rooftop position over the
body when at rest.
- adults (except Cicadas) feed on plant sap
- metamorphosis is gradual
Bugs, Backswimmers, Water Striders Hemiptera (“half-wings”)
- identified by a triangle on the back just behind the head. This is formed by the way
the insects fold their forewings when at rest.
- 2 pairs of wings; hind wings are membranous, while the basal half of the forewings
is hardened.
- metamorphosis is gradual
OTHER INSECTS OF IMPORTANCE
Termites: small, soft-bodied, pale with short, straight antennae. Flying forms have 2 pairs of wings. Do not have constricted waist like ants. Have sophisticated societies - the queen may live 10 years. Most of the 41 species live in the SE. Eat cellulose of the wood fibers making them bad for buildings but valuable for breaking down dead wood in the forests.
Springtails: tiny, wingless with prominent antennae. Forked structure allows them to “spring” into the air. Among the most abundant creatures on earth, are millions per acre. Immensely beneficial in breaking down leaf litter and fungi into soil components. Include “snow fleas.”
Bristletails: wingless, crawling, terrestrial with long segmented antennae and 3 long “tails”. Include silverfish and firebrats. Eat decaying plants outdoors and starchy substances including books,s, wallpaper, and clothing indoors. Among the most primitive of insects.

VT Bee Species Accounts: Exploring the Rich Diversity of Native Bee Species in Vermont
First Mock-orange Scissor Bee

iNaturalist for Vermont.
Who are the 350 wild bee species of Vermont?
(Chelostoma philadelphi) posted on
iNaturalist for Vermont.
I have discovered a new world that seems unmoving without a close, attentive look.
After observing over one thousand taxa of invertebrates in our 1.3-acre yard, including 98 bee species, over three years, I am dedicated to documenting and sharing the rich diversity of bee species in Vermont through the VT Bee Species Accounts project.
"VT Bee Species Accounts" (VBSA) Introduction
Vermont: Small state, Big Bee interest. The interest in pollinators, especially bees, is growing. Yet that interest seems outpaced by the need for an aggregate or consolidated source of the (documented) fabulous diversity and plasticity in how each species lives.
Key Points
- Project Objectives: The "VT Bee Species Accounts" aim to provide a comprehensive guide documenting the biology, behavior, and floral associations of every bee species known in Vermont in one document. It seeks to make this information easily accessible to society to promote understanding and conservation of bees.
- Document Categories: The spreadsheet includes various categories of information about each Vermont bee species (350+), such as nesting behavior, nest structure, foraging habits, life cycle, population status, and interactions with plants.
- Additional Tabs: In addition to the main spreadsheet, there are tabs for a VT bee checklist and phenology, bumblebee facts, "Did you know" bee facts, a bee dictionary, resources, and a bee-to-flower matrix.
- Dual Purpose and Impact:
- Consolidated Information: The VBSA provides a consolidated collection of detailed information on Vermont bee species, making it easily accessible to researchers, enthusiasts, and the general public. By offering comprehensive insights into the biology, behavior, and ecological interactions of each species, it aims to foster a greater understanding and appreciation of Vermont's diverse bee populations.
- Stimulating Observation and Research: A key objective is to encourage more people to observe bees and other insects in their natural habitats. By showcasing the fascinating lives of bees and the intricate relationships they have with their environment, the project aims to inspire curiosity and engagement in insect observation and conservation efforts. Additionally, the project seeks to stimulate further collation of existing research on Vermont bee species to enhance public knowledge and awareness.
- Why Learn About VT Bees*: Reconnect with the natural world and better understand the lives of other species, such as bees for their benefit and our benefit.
- Collaboration Invitation: You are invited to contribute to the project by providing data on bee species found in Vermont. Each contributor is encouraged to add information, with sources cited.
- Bernie's Bio: I have a passion for insects and helping others engage in nature exploration and observation.

Overall, the project is an effort to contribute to our understanding and appreciation of Vermont's bee species and how they live their lives. Collaboration and community involvement will undoubtedly enrich the dataset and contribute to its success.
Knowledge of the lives of Vermont bee species will promote the conservation and diversity of insects as part of the urban fabric.
Make discoveries for yourself as well as for scientists and conservation.

Here are some of the Resources I utilized the most so far.
I use The following tools to search for data to fill in data cells in the matrix.
Why learn about VT Bees
Molly Gloss in the novel "The Wild Life” writes, "But the conquest of the natural world has been the ruling passion of this modern society."
To which I rephrase and add - Now it must be our ruling passion to become reacquainted with and learn about the ways of the natural world; Our efforts must begin to repair our damage; aid or step aside as it repairs itself.
As Ed Yong in "An Immense World" writes, “We are closer than ever to understanding what it is like to be another animal, but we have made it harder than ever for other animals to be.”
We need to change our effect on other life forms. Getting to know them better is a good place to start.
I seldom can recall the names of the insects I view never mind ID them properly. Still, I wonder what name they might give me. Perhaps my token name, Bugeyedbernie would reflect their perceived meaning of my practice of observing them and seeking to learn about each species' differentiated life cycle - to learn truth and meaning from them and how they live their lives. As Gloss says, we can "find again our connection between ourselves and the natural world.”
From Gloss again, “I realize how little I know of their inner lives. Books and scientific knowledge - those things I have always believed in - cannot tell what the world looks like and smells like to them. Oh! I would like to enter their consciousness. I have a strong yearning to visit inside their minds, know their thinking and feeling - have them look at me and see something like themselves.”
Much is unknown and a lot of 'known to some but not published' in terms of the outside behaviors, life cycles, and needs of most insects, including the 300 or so bees known to be in Vermont. Every creature and human as well can only sense and experience a small portion of their surroundings. That portion is their Umwelt or perceptual world. As science and each of us, discover more about animals' senses, we can better understand their lives. As Ed Young in “The Immense World” states, Our senses filter in what we need. We must choose to learn about the rest.”
Amazing new details are discovered every day. I invite you to read about some of the details known about individual bee species (for they each differ dramatically in life cycle, behaviors, what they sense…).

Excerpt from, Song of Myself, 32
Walt Whitman
1819 – 1892
I think I could turn and live with animals, they are so placid and self-contain'd,
I stand and look at them long and long.
They do not sweat and whine about their condition,
They do not lie awake in the dark and weep for their sins,
They do not make me sick discussing their duty to God,
Not one is dissatisfied, not one is demented with the mania of owning things,
Not one kneels to another, nor to his kind that lived thousands of years ago,
Not one is respectable or unhappy over the whole earth.
