Oncocera semirubella is a very smart micro and appeared here for the first time last August when it was considered to be a wanderer from the Chilterns. With this second visitor it would be nice to think that it has now become established somewhere closer to home. Its larvae feed on bird's-foot trefoil and other vetches and there's no shortage of them around here. The completely grey Yponomeuta sedella was last seen in the garden in 2013 and seems quite uncommon in the county as a whole (there are fewer than 20 records for VC24). It certainly made a change from the ubiquitous evonymella which I get here in some numbers. Of the other Ermines, plumbella hasn't visited the garden trap since 2011 while the remainder (which in any case can't be safely separated without knowing the food-plant) generally only put in three or four appearances annually. Barred Rivulet is an occasional visitor to Westcott but this is another moth last recorded here in 2013.
Migrants so far this month have been limited to Dark Sword-grass (1st, 15th & 18th) and Small Mottled Willow (10th, 17th & 19th), along with more regular visits from Plutella xylostella, Udea ferrugalis and Nomophila noctuella. Silver Y has been seen but not regularly nor in any significant numbers, while during the daytime Hummingbird Hawk-moth is currently appearing every day on the buddleias and on several occasions there have been two at once.
