A year ago I brought over a dozen eggs from the Purple Hairstreak (Neozephyrus quercus) through winter to start raising them in spring. I did well at the beginning, but the adult caterpillars started to get ill. I only got one to pupate. It never hatched.
In autumn 2015 I managed to find close to 10 eggs again. I will definitely try my best to raise these eggs with care to get some butterflies in summer. It’s a species I’m looking forward to get some decent photos of. So far, I mainly managed to get ventral shots of the Purple Hairstreak. And it’s the dorsal, meaning the side visible when the wings are open, that’s something special in case of this species.
Here’s a couple shots from the eggs I found in autumn. One photo shows a caterpillar from a year ago, and how they are in disguise looking like a part of their host plant. Should you need some tips finding eggs have a look at this post.
