Longhorn Moths

From a month ago: a pair of Nemophora degeerella (Lepidoptera: Adelidae) mating.  This summer whirling swarms of between 3 and about 20 of these moths have been quite common, usually in sheltered clearings between the trees.  I was walking through one such swarm when these two suddenly dropped out of the swarm and fell into the long grass.  The one with the longer antennae is the male.
