The phorid material was collected in 1986 and 1987, using yellow plastic bowls attached to crowns of pines (Pinus silvestris) or placed on the ground in pine plantations, from April to October. Triphleba trinervis occurred only in autumn, while T. opaca, T. nudipalpis and T. minuta occurred both in spring and autumn. Among the latter group of species, T. opaca had its abundance peak in spring, but T. minuta peaked in autumn. T. luteifemorata and T. lugubris were caught from the late summer to the end of October. Only a few specimens of T. crassinervis were observed from May to June. The phenology of eudominant species Triphleba opaca and T. trinervis was characterized by one abundance peak. The majority of the Triphleba species in this study are known to occur during the low-temperature period (November–March). T. trinervis, a late-autumn dominant, clearly preferred temperatures lower than those preferred by T. opaca, a spring dominant.
