Map-winged Swift (Hepialus fusconebulosa) f. gallicus
Herts Moth Group meeting - Sherrardspark Wood - 14/05/11
The best moth of the night a Map-winged Swift which I rather keenly netted and suspected it to be yet another Common Swift! indeed it wasn't but my first ever Map-winged Swift! it was also a first sighting for many of the other keen people who turned up and braved possibly the wettest, windiest and coldest night we've experienced for a long while!
It is also of a different form (f. gallicus) having different markings to a typical specimen.
From what I know it feeds on the roots of Bracken, which there is plenty of at Sherrardspark Wood, why this moth isn't at Thorndon Country Park (the biggest space of open Bracken in the County of Essex) is beyond me! perhaps it is, perhaps we have yet to find it, who knows!
Other species of note were Brindled White-spot and Lobster Moth.
