Species

Biology

A flower-living species that is often particularly common in flowers of Rosaceae.

Distribution

Throughout Europe, except the north.

Recognition

Body largely light brown with yellow markings on pronotum; legs yellow with femora shaded brown, antennal segment III yellow; forewing weakly shaded with dark setae. Head with 2 pairs of ocellar setae, pair III shorter than side of ocellar triangle and arising on anterior margins of triangle. Antennae 7-segmented, III & IV with sense cone forked. Pronotum with many transverse striae, 2 pairs of posteroangular setae long. Metanotal median setae not at anterior margin; median sculptured reticles elongate; campaniform sensilla present. Forewing first vein with 3 setae on distal half. Abdominal tergite II with 3 setae on lateral margin; V-VIII with paired ctenidia laterally, on VIII posteromesad to spiracle; posteromarginal comb on VIII present laterally. Sternites with no discal setae. Male smaller and paler than female; sternites III-VII with transverse glandular area.

Related species

The most closely related species is one found only in North America. However, other common European flower-living species, such as T. fuscipennis, with which T. major co-exists, are also very similar but have different sculpture on the pleurotergites and the lateral margin of tergite II with a row of 4 setae.
