26 March 2012 – Moth Equinox

The Satellite (Eupsilia transversa)

The days have been warm but the nights have still been leaving a frost at dawn so the assumption has been that it is probably too cold for the moth trap.  The trial run at the weekend produced two new species so I was obviously wrong.  The Satellite and the Twin-spotted Quaker have been positively identified despite the Satellite arriving in two colourways – gold stigmata and white.The Latin name is Eupsilia transversa (very bald  from eu – well; psilos – bare; transversus – from the transverse fasciae on the forewing). I assume the little extra stigmata next to the larger one give it its common name (see photos).

The Twin-spotted Quaker (Orthosia munda) is another variable species with forewings of different colours.  The twin-spots aren’t always there apparently.  The Latin name comes from orthosis-making straight and mundus = neat and tidy.Why so many Quakery moths?  They are all quite discreet and unshowy as moths….can this have anything to do with it?  Hebrew Characters and Small Quakers made up the numbers – all safe because the bats haven’t yet taken to the air.  But that can’t be long if this extraordinary warmth continues.In June there will be a moth-trapping and report every day….
