"So, naturalists observe, a flea has smaller fleas that on him prey; and these have smaller still to bite ’em; and so proceed ad infinitum."

September 26 - Carnus hemapterus

Carnus hemapterus is a species of fly where the adults (the imagines, plural of imago), feed on the blood of nestling birds, particularly those of large birds such as owls or falcons. Larvae are birthed by females and feed just on the detritus in the nest, but then the development and emergence of the imagines coincides with the hatching of the birds. Both winged and unwinged flies may be present.
