ENV: Not-Really-a-Cat Friday

The genus Asterocampa -- the Emperor Butterflies -- can be holy snuggles to identify. There are a few behavioral clues, but you're more often left to sort out which one has broken forewing bars, who has white, black or blue-eyed spots, and what foodplants are available. So with some luck and patience and a horde of both Empress Antonia (our race of the Hackberry Emperor) and Tawny Emperors a few weeks ago at Zilker Gardens in Austin, i was able to catch one of each in the same frame. I'll let you dig out the books and figure out which is which -- the practice will help you in the future. Click on the picture to view a large version. Just be thankful i wasn't able to corral an Empress Leilia in the photo as well.

Be sure to check out The Friday Ark at The Modulator.
