During field studies conducted in south-central Michigan in 1977 and 1980. 109 specimens of Neopyrochroa flabellata were observed and collected at filter papers baited with cantharidin. Only the two highest concentrations used (39.2 mg. 392 j.Lg) elicited responses. and the beetles did not prefer one over the other. In the 24-h studies, most specimens were observed at the cantharidin baits between dusk and 0100 hrs (61 %; n = 14). and 0430-0630 hrs (26%; n = 6). Only two of the 109 specimens were female.
