A small moth with ridiculously long antennae: Nemophora degeerella, the longhorn moth. Only in the male are the antennae this long (4 to 6 times body length), in the female they are much shorter (only 1 times body length).
This afternoon I came across several males in the bushes near the ice house. Further along my walk I saw some females, but I didn't get any photos of them.
