Stigmella incognitella

Alternative names
Grey Apple Pigmy
Description

Many Stigmella species are almost impossible to identify as adults, but are easier to record from the leafmines created by their larvae. The larvae of Stigmella incognitella mine the leaves of Apple. The mines are found between veins. The initial gallery is narrow and then forms an orange-brown blotch.   

Identification difficulty

Adult Leafmine

ID guidance
Recording advice

Records of the leafmine should include a backlit image of the mine showing the frass pattern as well as a picture of the leaf.  The record should also include a note of the host plant on which the leafmine was found.

Habitat

Where Apple is found.

When to see it

Leafmine: June-July, October-November.

UK Status
