Yesterday I pictured some warblers enjoying winged termites, which kept fluttering through the air.
Here are some of the termites on the ground. Birders often call these eruptive spring events “hatch-outs” as all sorts of birds come for the feasting at ground level or close to it.
Both male and female reproductive caste members of a termite colony have wings. Some of the wings seem longer than others: could that be sexual dimorphism? They’ll take off searching for a mate.
Once mated, they lose their wings, which are pointless underground.
These might be Eastern Subterranean Termites.
