Barred Red Hylaea fasciaria
Wingspan 27-40 mm.
An inhabitant of coniferous woodland, this species has a green form (ab. prasinaria) in addition to the typical reddish form, which is found occasionally in the south.
Found throughout most of Britain in suitable habitat, it can be reasonably common.
The caterpillars feed on a variety of coniferous trees, including Scots pine (Pinus sylvestris) and Norway spruce (Picea abies).
