The Larval Instars of Orthopodomyia pulchripalpis Rond. (Diptera Nematocera)

Abstract

Orthopodomyia pulchripalpis was first recorded in Britain by MacGregor (1919), who found it, in association with Anopheles plumbeus Steph. and Aëdes geniculatus (Olivier), in a water-filled hole in a beech tree in Bpping Forest. He described it as a new species, 0. albionensis; but later Edwards (1922) showed it to be synonymous with 0. pulchripalpis Rond. Keilin (1927, 1927 a) found larvae of 0. pulchripalpis in a water-filled hole in a horse-chestnut tree in Cambridge, thus establishing a second locality for this mosquito in Britain. Beattie and Howland (1929) recorded it from water-filled holes in beech trees at Burnham Beeches, Buckinghamshire. In each case it was found in association with Anopheles plumbeus and Aëdes geniculatus.
