A species of the arctic-alpine zone. Small numbers of records from Scotland and Cumbria. Most records are at high altitude but a few are lower down (Musgrove, 2024). In the female the head, including the antennae, and at least most of the thorax and underside of the abdomen are coloured reddish-yellow. The stigma is pale. Males are probably indistinguishable from Euura nubium.

Euura reticulata larvae feed on bilberries.

Size: Female: 4.0 - 5.5mm.
