Note on bevavior:
They're on mule fat (in the butterfly garden).
Two species: P. mildei with orange antennae, P. thisbe with black.
Walking by the bush, I bumped into it with my hat and sent maybe a dozen of them
off into the air. The all-male diners were absolutely non-aggressive and quickly returned.
