Considering the flying activity or phenology of the sphecoid wasps we can establish their repeated culminations at the middle of May, June, July and August with species numbers 15, 23, 13 and 15, respectively, otherwise, one to seven sphecoid species were trapped from the third decade of May to the second decade of October. The curve of Fig. 3 insinuate a rather pulsating activity from decades to decades which, we firmly suppose it, does not reflect the real flying activity of sphecoids. A significantly more balanced curve would indicate the true phenology of these wasps. Table 6.
