This is the species that so enchanted all of us a month or so back when millions (literally) flew north to our area and beyond in two giant waves. We were all seeing 5,10, 100 per day. Now we see one or two, or none! However, the stinging nettles which were full of eggs, now have red admiral caterpillars, although numbers are greatly diminished. Nonetheless, the remaining caterpillars are getting bigger and will soon form a chrysalis.
