284 Hylaea fasciaria (Barred Red)

70.284 Hylaea fasciaria (Barred Red)

fw: 17-21mm; Jun-Aug; Scots pine (Pinus sylvestris), Norway spruce (Picea abies); common in native pine forest and conifer plantations throughout GB.

Hylaea fasciaria (Barred Red) §2 female

ID: Typically varies from reddish-brown to dull grey, with two curved crosslines, concave towards the forewing base, and bordering a slightly darker median fascia. Plagodis pulveraria (Barred Umber) has similar colour and pattern but it has a much straighter proximal line and a very jagged distal line. The continental form H.fasciaria prasinaria is green and has been reported rarely from SE.England – it could be confused with Campaea margaritata (Light Emerald), but this has much straighter cross-lines and a red mark at the forewing apex.
