Here’s another intimate moment between two Police-car Moths from my backpacking trip the other weekend. They really were copulating everywhere. The males will carry their partners through the forest as they both continue to feed on nectar. Eventually they will detach and the female will seek out a Bluebells plant (Mertensia) or some other member of Boraginaceae to lay her eggs.

Happy National Moth Week!

The Police-car Moth had a really big year this summer. During our weekend backpacking trip, we must have seen 30 or 40 individuals! These day-flying moths are found in the Northwest, south to Nevada and New Mexico. They tend to be found at mid- to high-elevations in the middle of summer when meadow plants are in full bloom. The adults feed on nectar and copulate for their month-long lives before laying their eggs on any number of Boraginaceae plants (bluebells, houndstongue, Lithospermum, etc.). The larvae will then hatch and eat like crazy until they hibernate as caterpillars, waiting for snows to melt. These two individuals were just hanging out and happily permitted me to photograph their – ahem – intimate moment.

This individual is a female and will probably be accosted by a hot-and-ready male at any moment.
