|scientific name Haplothrips leucanthemi |
Crysanthemum leucanthemum, Trifolium sp. (Chiasson 1986), red clover (Stannard 1968).
Body varies around 2mm in length and is dark brown except for antennal segment 3, the fore tarsi, and the apices of the fore tibiae, which are yellowish brown. The head is somewhat longer than broad, and is covered with weak transverse striations. Ocelli are present, and the postocular setae are minute. Antennal segment 3 has 1 inner and 1 outer sense cone, segment 4 has 2 inner and 2 outer sense cones, segment 7 has a narrow pedicel, and is broadly joined to segment 8. The major setae on the pronotum are short and pointed, though the anteromarginal setae are minute. The metanotum may be so weakly striate that it appears smooth. Each fore tarsus has a small tooth. The setae on the basal wing vein are small and pointed. The pelta is triangular and has several longitudinal striations (Stannard 1968).
This species has spread across the temperate parts of the world parthenogenetically, in Trifolium flowers (Mound and Marullo 1996). It was introduced to North America from Europe (Thomasson and Post 1966).
This species feeds on pollen (Chiasson 1986).
