FIGURE 1. Antennal features of male Scathophaga stercoraria (Linnaeus, 1758). A. Lateral view of the male head with antennae located between compound eyes. B. Posteroventral and dorsolateral surface of antennal funiculus. C. Anterodorsal and dorsolateral surface of antennal funiculus. D. Anterodorsal surface of antennal pedicel and scape. E. Posteroventral surface of antennal pedicel and scape. F. Antennal arista. G. Magnification of mechanoreceptor on antennal pedicel. (Abbreviations: Ad (anterodorsal surface); Ar (arista); Ch (chaetic sensillum); Dl (dorsolateral surface); Fn (funiculus); Pd (pedicel); Pv (posteroventral surface); Sc (scape); SP (sensory pit). Scale bars: A. 1 mm; B–E. 100 µm; F. 250 µm; G. 100 µm.)
