|scientific name Aeolothrips fasciatus |
Taraxacum officinale, Trifolium repens, Epilobium angustifolium, Grasses .
Reported as March to October in some parts of North America (Bailey, 1951).
Identification of this species is difficult as A. fasciatus constitutes a species complex, and is difficult to differentiate from A. intermedius, which is a mostly Palearctic species (Heming). The body is generally a dark black-brown with red subintegumental pigments, and is usually over 2mm in length. The head is weakly transverseleystriated and is wider than it is long. Antennal segment 6 is approximately the same length as 7, and segments 8 and 9 are reduced in length. Sensoria on segments 5 and 6 are small and circular, and the third antennal segment is pale yellow or grey with a brown tip. The forewings each have 2 distinct cross bands, and are white in the basal fourth of the wing (Stannard, 1968).
This species is both a pollen feeder and a predator (Chiasson, 1986) and can produce more than one brood of young per season (Bailey, 1951).
A. fasciatus feeds on pollen and flower tissue, but it also preys upon various arthropods, including onion thrips, Frankliniella moultoni, and Sericothrips variabilis (Bailey, 1951).
This species is found in Alberta (Chiasson, 1986), and is widespread across North America (Bailey, 1951).
