Dear Sir,
We saved this specimen from certain death by car tire and are wondering if you can identify him. I thought it might be a male Dynastes tityus but the yellow coloring does not seem to match that species.

Goldsmith Beetle

Dear Jen,
Your request was sent on the first day of our much needed holiday, and we just returned to the office Tuesday, so we are embarking upon the impossible task of responding to requests that arrived in our absence and posting the most interesting submissions.  Your Goldsmith Beetle image is gorgeous, and warrants featuring on our scrolling feature bar for a spell.

Awww, thanks! 🙂

Found this large Sphinx moth on my front porch last night in Carrboro NC. My best thoughts were it might be a Rustic Sphinx moth.

Carpenterworm Moth

Dear Mary,
Though it resembles a Sphinx Moth, this is actually a Carpenterworm Moth,
Prionoxystus robiniae, in the family Cossidae, which we verified by matching your individual to this BugGuide image.  According to BugGuide:  “Larvae bore in wood of living deciduous trees: locust, oak, chestnut, poplar, willow, maple, and ash.”  BugGuide also notes:  “Large, might be mistaken for a sphinx moth. ”  We will be featuring your posting as our Bug of the Month for June 2017.

We found one of these moths, figured out the name through your page, but it doesn’t seem to want to fly away. We noticed these egg looking things on its body. What are they? Should we keep it safe in a terrarium? If so, what do they eat?
Thanks for your help!

Ceanothus Silkmoth

Dear Susan,
Though this resembles a Cecropia Moth, that is an eastern species and this is a western relative, the Ceanothus Silkmoth.  Male Giant Silkmoths have more feathery antennae as that is the scent organ that allows him to locate a female through the pheromones she releases, so we believe this individual is a female.  Giant Silkmoths do not feed as adults, and they live for about a week on stored body fat.  Flying takes energy, and a female filled with eggs is much heavier, so she is reluctant to fly unnecessarily.  Often a newly emerged female will release some unfertilized eggs before attempting to fly, and we suspect that is what you have documented in your image.  Though the eggs pictured on Liang Insects are more brown, it is possible that freshly laid eggs are lighter in color.  If you keep her in a terrarium, make sure it has a screen lid.  She may attract a mate.  You might want to consider releasing her and letting nature take its course.  Again, she cannot eat. 

Ceanothus Silkmoth, presumably with eggs.

Ed. Note:  Since Ceanothus Silkmoths are currently in flight on the west coast, we will feature this posting for a spell.
