Distinguishing features

Both sexes with fore wings bearing two transverse dark bands, apical ring vein pale. Body and legs brown, antennal segment I pale, II–III largely yellow; abdominal segment X variable but often much paler than VIII–IX. Antennae 9-segmented, segment III with linear sensorium almost 0.5 as long as segment, IV with sensorium more than half length of segment and curved distally; segments V–IX forming a single unit with V considerably longer than VI–IX. Head and pronotum with no long setae; eyes prolonged on ventral surface, maxillary palps 3-segmented. Fore tarsus apically with stout recurved ventral hamus. Metanotal reticulation weak. Marginal setae on sternites arising at or close to margin; sternite VII paired accessory setae arising well in front of margin.
Male tergites IV and V with paired dorsal tubercles; setae at base of paired claspers on tergite IX shorter than clasper, with stout curved seta lateral to clasper.

Related species

Rather more than 100 species are placed in the genus Aeolothrips, mostly from the Palaearctic Region but with about 30 from the Nearctic including the western USA. A. ericae is a member of the Eurasian species-complex that includes A. intermedius and A. fasciatus Linnaeus. However, the males have a pair of very stout setae anterolateral to the bifurcate claspers on the ninth abdominal tergite. Females are readily distinguished from similar looking species in Britain by the pale colour of the basal antennal segments and the tenth abdominal segment that is often paler than segments VIII and IX.

Biological data

Closely associated with the flowers of Erica and Calluna [Ericaceae], but also found in the flowers of various Fabaceae. This species is presumed to be a facultative predator, feeding on a mixed diet of pollen and the larvae of other thrips in the flowers where it breeds.

Distribution data

Described from British material (Bagnall, 1920), and widespread in Britain from Kent to Caithness, although not recorded from Ireland (Mound et al., 1976). This thrips occurs widely across Europe from Norway southwards. It has also been introduced into North America.
