Red Admirals don’t overwinter this far north. They come north every spring – in very variable numbers – and after a generation or two – many fly south again in the fall. (Bugguide)
They prefer sap from trees, animal dung, and fermenting fruit, but will also take nectar from flowers. (BAMONA)
They usually show up here in very early spring – March or April. Some years we see almost none. Other years there are many. We’ve had two years where we saw thousands. One of those years was soon after we first bought the farm. We still had many fences lined with stinging nettles. That year every nettle plant was stripped of its leaves, and dripped with chrysalises.
