Biology In Europe Cernosvitov and Evans (1947), Gerard (1964), and Tetry (1938) re- ported the species from garden soil, meadows, and orchards. With the exception of Bouche's (1972) study in France, Ap. icterica has been reported infrequently and in low numbers in Europe. The species is obligatorily amphimictic (Gates, 1968). Ap. icterica is not known to have any economic importance. Range A native of Palaearctis, Ap. icterica is now known from western Europe and North America (Reynolds, 1976e; Schwert, 1977)..
