Object of the Month: 08/2015

What is it?:

Sphinx moth

Pachysphinx Modesta
Big Poplar Sphinx Moth


11.5 cm wing span (4.5 inches)

That startling movement in front of your face one of these dark summer nights just might by a big poplar sphinx moth. This is the time of year we see those moths on our screen doors, windows and sides of buildings.

Big poplar sphinx moths get their name from their larval food source. Caterpillars eat the leaves of aspen (poplar or popple) and willows. And it’s on those same trees at this time of year that females are laying the eggs for the next generation to hatch from next year.

Follow this link to read about how one classroom of students discovered big poplar moth eggs and studied them until they hatched as caterpillars.

This link will take to you a gallery of images of these moths found out in their natural habitat.

Use the box below to type in your own description and comments about this unique insect for other museum visitors to read.

that although my wings are brightly colored and I'm quite a bit larger than most of my family and friends, I fooled you as I'm actually a moth and not a butterfly at all.

i love the soft pink in their wings, especially on the bottom wings. this seems really stupid, but i would look for it if it as a butterfly but i think moths are really gross so if i see it, cool. if i dont, oh well :(

It did kind of startled me too because the sphinx is an unusual thing to see. Not the kind of insect you see everyday.
