Chalk downs in Southampton
Natural HistoryOr that’s how it seems when a micro-moth of the chalk ends up in Bevois Valley. Emptying a very meagre moth trap last night the one notable capture was a single Cochylis hybridella.
According to HantsMoths this micro is local on chalk downland, woodland on chalky soils and sand-dunes throughout much of southern England and southern Wales, with records north to Cheshire. In Hampshire and on the Isle of Wight taken occasionally at light, mostly in a band from Romsey in the west to Southsea in the east, perhaps overlooked elsewhere. Wingspan 12-16 mm. Distinguished from C. dubitana and C. atricapitana by the white thorax [Bradley]. Larva feeds within seedheads of Bristly Oxtongue, Hawkweed Oxtongue, several species of Hawk’s-beard, over-wintering in a cocoon.
Still, given we don’t have any of the food plants it seems a minor issue that we don’t have any chalk. Or downland.
This moth could have originated locally as most of it’s food plants occur in Southampton area, especially the Hawkweed Ox-tongue.
