Hi all, Todd Stout Lepidopterist extraordinaire, sent this out as an email. I thought you’d like to see it here.
By the way, Todd has an incredible site on Raising Butterflies. You really need to check it out.
“Here’s a short video I just uploaded on how to find hibernating Viceroy, Admiral and/or Red Spotted Purple caterpillars in rolled leaf hibernacula during the fall, winter, and/or early spring months. Although this video specifically addresses finding Lorquin’s Admiral (Limenitis lorquini burrisoni) hibernacula in Idaho, it can be applied to other Limenitis populations as well where you have the opportunity to seek out isolated willows, aspens, choke cherries, or service berries.”
