They Didn't Get the Memo

They didn't get the memo. Summer is over. Fall is underway. Winter is coming (Dec. 21). But the Gulf Fritillaries (Agraulis vanillae) are still laying eggs on the passionflower vine here in Vacaville, Calif. The eggs are hatching. The caterpillars are...

No Gulf Fritillary will ever eclose from this chrysalis. Note the parasitoid hole. It was a large parasitoid--a big tachinid fly or an ichneumonid or wasp--says Art Shapiro, UC Davis distinguished professor of evolution and ecology. (Photo by Kathy Keatley Garvey)

Oh, the joys of rearing monarch butterflies. Not for commercial purposes. For conservation purposes. For a couple of months now, we've been watching the monarch caterpillars slowly disappearing from our milkweed plants.  We'd see fifth instar 'cats...
