Spicebush Swallowtail Caterpillar

Spicebush Swallowtail Caterpillar

Dear Ron,
This is the Caterpillar of a Spicebush Swallowtail, and it is widely accepted that the caterpillar has evolved so that the false eyespots on the caterpillar act as a form of protective mimicry by potentially fooling predators into thinking that their prey might actually be a larger and potentially threatening predator itself.  According to BugGuide:  “Caterpillar hosts: Spicebush (
Lindera benzoin), Sassafras trees (Sassafras albidum), Pondspice (Litsea aestivalis) Red, Swamp and Silk Bays (Persea spp.); perhaps prickly ash (Zanthoxylum americanum), Tulip tree (Liriodendron tulipifera), Sweetbay (Magnolia virginiana), and Camphor (Cinnamomum camphora).”  Do you have any of those plants in your garden?

Hi, I live in Southern New Hampshire and found a very unusual bug (I believe a moth who had lost parts of it’s wings) on the head board of my bed the other night. I love to have it identified. I gently tapped it with a piece of paper, and it fell to the floor. When I’d returned to the spot a couple of minutes later, it was gone. It had a medium brown, fuzzy body and a large lime green marking on each side of its body.

Spiny Oak Slug Moth

Spiny Oak Slug Moth

Dear Kathleen,
This is a Spiny Oak Slug Moth,
Euclea delphinii, a species that according to BugGuide:  “adults are nocturnal and come to light.”  The Spiny Oak Slug Moth caterpillar should be handled with extreme caution as it is one of the stinging caterpillars that could cause a significant reaction in sensitive people.

Pine Chafer

Dear D. Mullen,
Your beetle is
Polyphylla fullo, commonly called a Pine Chafer.  According to NatureSpot, it is found:  “In and around pine woods especially on sandy soil but usually only encountered as a vagrant in Britain.”  This is one of the beetle species that is known for producing very audible sounds by rubbing body parts together, a process known as stridulation.

I work at a local YMCA and some kiddos found this dude just hanging out on the side of a storage shed. Middle of the morning, really hot ouside, just happened today! I didn’t see him moving at all.. came back a couple of hours later to take another pic and he was only moved slightly. Thanks for your help!

Male Dobsonfly

Male Dobsonfly

Dear Ashleigh,
This is a male Dobsonfly, one of our most common summer identification requests.

Thanks for letting me know. What do they do? I can’t believe I’ve never seen one before in my life.. pretty crazy looking.

Dobsonflies are generally found not far from a source of water.  The larval Hellgrammites are used as bait by anglers.  Adult Dobsonflies do not eat, living long enough to mate and produce a new generation.  Male Dobsonflies have impressive mandibles that are ineffective in terms of biting to defend themselves, while female Dobsonflies have more utilitarian mandibles that could produce a pinching bite if carelessly handled, but they are still considered harmless toward humans.
