Periclista lineolata

Recorded widely across England and Wales north to Northumberland, although with no records from south-west England to date. No recent Scottish records although Benson (1952) described the range as extending north to Perthshire (Musgrove, 2023).

The head and the abdomen are dark. The tergites have pale apical margins. The thorax is polished without punctures. The stigma is dark and the legs have black femora, white tibiae (apically brown) and brown tarsi. The antennae are shorter than P. pubescens and segment 3 is clearly longer than segments 7 and 8 combined.

Periclista lineolata larvae feed on sessile and English oak. This species has the branched bristles dorsally with the branches about the same length as the stems. The anal segment has a row of six unbranched bristles with a small forked bristle on either side posterior to the row. The head is also dark.
