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.
