70.264 Deileptenia ribeata (Satin Beauty) 1940
fw: 18-26mm; Jun-Aug; various trees predominantly conifers; local to common mainly in coniferous woodland in England, Wales and S.Scotland.
ID: Probably best distinguished from similar species by wing-shape, having a more curved costa and rounded apex; its forewing markings can be quite similar to P.rhomboidaria (Willow Beauty), but its hindwing appears much less well-marked than its forewing and this contrast between forewing and hindwing may be a good feature? The only specimen I have yet obtained was very worn and only identified after genital dissection.
