Diurnal and nocturnal biting activity of flies (Diptera) in western Uganda

Day and night catches of biting flies (excluding Culicids) were made from bullock, buffalo and at light near Lake Edward, western Uganda, between July 1966 and August 1967. The 39 species caught were classified according to the time of day at which they bit. The seven groups and the most commonly caught species are as follows: group 1, Ceratopogonids (purely nocturnal) and Glossina fuscipleuris Aust., Stomoxys ochrosoma Speiser and Haematobosca squalida (Grunb.) (diurnal and nocturnal); group 2 (early morning peak), Haematobia minuta (Bez.), H. spinigera Mall. and H. thirouxi (Roub.); group 3 (mid-morning peak), females of Tabanus taeniola P. de B. and T. thoracinus P. de B.; group 4 (mid-morning and late evening peaks), Haematobosca latifrons (Mall.) and males of G. pallidipes Aust.; group 5 (early morning and evening peaks), Stomoxys taeniata Big., S. nigra Macq., S. inornata Grunb. and S. omega Newst. and females of Haematopota brunnescens Ric. and H. patellicorne (End.); group 6 (midday to mid-afternoon peak), females of G. pallidipes, H. brucei Aust., T. par Wlk. and Chrysops distinctipennis Aust.; and group 7 (progressive increase in biting from morning to evening), G. fuscipes Newst. and S. calcitrans (L.) [cf. RAE/B 54, p. 35].
