Phyllonorycter tristrigella

(Haworth, 1828)

Wingspan 7-9 mm.

One of the more distinctive of the Phyllonorycters, this species has two complete bands across the forewing and then a chevron-like mark nearer the wingtip. It also lacks the dark fringe line often present in other species.

The larvae feed on elm (Ulmus), creating a long, narrow blotch mine on the underside of a leaf between two veins.

There are two broods, with adults at large during May and again in August. The species is relatively common in mainland Britain northwards to southern Scotland.
