Habrodais

Habrodais grunus

A very strange species, often common to abundant (but occasionally rare) and demonstrably long-lived, yet not known to visit flowers (or anything else resembling a food source) at all. It has a very short proboscis. There is a single brood, emerging in late spring to early summer, estivating in cool, shaded locations on the forest floor (e.g. inside bramble tangles), then re-emerging in autumn to breed - how do they do it? The adults are active in late afternoon and on into dusk, flying around the host tree.
