4.068 Trifurcula immundella (Zeller, 1839)
< back
mine blackens


Food Plant: Cystisus scoparius (Broom)

Egg: on branch

Mine: September-May

Notes: A conspicuous egg (as shown, at left of mine), which indicates this species and not the similar looking mine created by Leucoptera spartifoliella. A long black straight gallery is formed, which passes down the twig initially (which enables distinction with the similar mine of Leucoptera spartifoliella). The mine then changes direction and the spaces between the ridges stain black as the mine fills them. The branches may appear stained black as the mines develop. The larva is yellow.

Data: 17.xi.2020, Bagley Woods, Berkshire, VC22
