Stigmella sorbi

Alternative names
Barred Rowan Pigmy
Description

Adult Stigmella are very difficult to identify and this species is best recorded as a leafmine on Rowan, or bred through, the adults are relatively large and often paler than many other Nepticulidae, with pale brownish wings and a broad, poorly defined creamy fascia.  The mine is a narrow gallery soon becoming a large round blotch with scattered frass, and these are very obvious, often several to a compound leaf.

Identification difficulty

Adult Leafmine please state the host species (i.e. usually Rowan)

Recording advice

Adults can only be reliably recorded when bred from leafmines on Rowan.  If recording the leafmine please supply a backlit image and state the host species (i.e. usually Rowan).
