Keep an eye open for those tricky spring species

We all need to be very vigilant when checking the trap at this time of year as some of the more uncommon spring species can be easily overlooked or misidentified in among the more common species. The following list shows what we should be checking for in the trap.

·         The Small Quaker can be a very numerous species, but check them carefully as there might just be the similar looking, but very uncommon Blossom Underwing in amongst them.
·         Clouded Drab and the Twin-spotted Quaker both have very variable colour forms and one colour form of Clouded Drab in particular can look like a form of Twin-spotted Quaker, so we need also to be on our toes here.
·         The Powdered Quaker will be on the wing soon. This species has a dusting of speckles and is slightly bigger than the Common Quaker, but if the speckles aren’t very prominent it can easily be mistaken for the latter.
·         The Lead-coloured Drab has been recorded in a few sites in the east and south of the county. This species can easily be confused with the Common Quaker, so all individuals much be checked thoroughly. The Lead Drab has a more even lead colour and the apex of the forewing is more rounded. It would be great if we could get some more confirmed records of this species, so again, be vigilant.
·         Our first two specifies of Pugs are also on the wing now, i.e. Brindled Pug and Double-striped Pug and while they’re not that similar, care should be taken with id.
·         Several species of Agonopterix and Depressaria are also on the wing at this time of year, many of which can be confused with others.

If you’re in any doubt with identification, of any of the above species, as always, send me a photo and I’ll do my best to confirm it for you.  

Other good early species to look out for now are; Pine Beauty, Brindled Beauty, Glaucous Shears, Broom-tip and Grey Birch.

Happy mothing
