Print Fact SheetChirothrips manicatus

Distinguishing features

Female fully winged (rarely micropterous), but variable in size. Body, antennae and legs brown, tarsi paler, fore wings light brown. Antennae 8-segmented; segment II asymmetric with prolonged external margin bearing terminal seta-like sensorium; segments III–IV with sense cone simple and stout. Head small, prolonged in front of eyes with long preocellar area; 3 pairs of ocellar setae present, pair III anterolateral to fore ocellus; maxillary palps 3-segmented. Pronotum trapezoidal, 2 pairs of prominent posteroangular setae. Metanotum reticulate, sculpture forming arches around posterior midpoint; median setae not at anterior margin, smaller than lateral pair. Fore wings pointed; first vein distal half with 2 setae, second vein with 4 setae. Abdominal tergites with transverse sculpture lines medially; posterior margin with craspedum of weak lobes; ovipositor weak with faint teeth. Posterior margin of sternites with distinctive tubercles.
Male micropterous, with minute wing lobe; head without ocelli; sternites III–VII with small circular pore plate. 

Related species

Currently there are 42 species worldwide placed in the genus Chirothrips. In contrast, zur Strassen (1960) treated the genus in a broad sense, with a key to 50 species, whereas Bhatti (1990b) placed several of the species into six new genera, and the generic classification was further reviewed by Nakahara & Foottit (2012). From Europe, zur Strassen (2003) recognised 14 species of Chirothrips, of which five have been taken in Britain. C. manicatus is very common in Britain, where it is the species of Chirothrips with antennal segment II produced outwards that is most likely to be encountered.

Biological data

Each larva feeds and pupates within a single flower of its host plant, and these include Poaceae in several genera such as Alopecurus, Dactylis and Poa (Minaei & Mound, 2010).

Distribution data

Abundant throughout Britain and the island of Ireland, and across the Holarctic Region (Mound et al., 1976; O'Connor, 2008), but also introduced to Australia, New Zealand and Hawaii.
