Gatekeeper ab?

[David M]

Had this image sent to me the other day. It's a very pallid form of Gatekeeper which is surely an ab?

I'm not seeing a similar one in the species-specific albums so does anyone know what form of aberration it might be?

Hi David,

I'd say this was referable to ab. albidus (Cockerell, 1889).

= albida Castle-Russell.Entom.1904.37.p.127.
= virginalis Oberthür.Lep.Comp.
= alba Leeds.Proc.S.Lond.Ent.&.Nat.Hist.Soc.(1948-49)1950.p.89.

Good hunting.

Kind regards. Mark

Thanks, Mark. That certainly looks the right match.
