Keep looking for those Micros

It's worth tapping trees this month for 2nd generation Phyllonorycter and other Micros.  Most trees I swept this afternoon produced at least one Phyllo, and the Alders held 10s of Argyresthia goedartella as well.  Highlights of a walk around Dingestow Court Lake were 3 Bohemania quadrimaculella from Alder, a Phyllonorycter stettinensis mine on Alder, 1 Bucculatrix ulmella and 1 Caloptilia robustella from Oak, and another host Oak for Yellow-legged Clearwing with 1 exuvia found.  Supporting cast included many Phyllonorycter harrisella from Oak and P. rajella from Alder, and several Cameraria ohridella from Horse Chestnut.  A Mompha langiella from a twiggy Oak trunk is the 3rd time this year I have beaten this scarce Enchanters Nightshade-feeding Micro from Oak at Dingestow...

Bohemannia quadrimaculella - a relatively large member of the Nepticulidae

Bucculatrix ulmella - an obscurely-marked Oak feeder

Caloptilia robustella - a clean-cut costal blotch, no tornal spot, and non-contrasting tegulae all suggest this species
