White-lined Sphinx caterpillars marching, Southern New Mexico
Hi bug people
Know you have many images of White-lined Sphinx caterpillars but thought you might like to see these. We’ve had an unusually wet summer, which I guess accounts for the huge numbers – hundreds of them on the move this morning. The first two shots are of the “march”, the last two show both yellow and green forms.

Hi Jaymie,
Whitelined Sphinx Caterpillars are especially plentiful in arid areas of the Southwest this year. There was even a broadcast news story on the Los Angeles evening news.
