The Orange Swift Moth Triodia sylvina is one of five British species belonging to
the family Hepialidae. The larvae of these comparatively
primitive moths are unusual as they don’t feed on leaves – instead, they live
underground, feeding on roots, and take a long time to develop prior to
pupation (2 years). Confirmation of this would presumably have required the
study of captive specimens! Adults are not equipped to feed, relying on
nutrients stored during larval development to sustain them for long enough to
be able to breed. These moths are readily attracted to artificial light. The
male in the photographs was in pristine condition and was therefore believed to
have emerged recently.
