Description
 
 

There are 41 species of Leskia worldwide. There are 3 species in North America north of Mexico, one in the west, two in the east. Only Leskia similis occurs in Minnesota.

Leskia similis is an uncommon, small, yellow, tachinid fly. The face is convex when viewed from the side, at least on the lower half. The eyes are bare, not covered with hairs (setae). The front plate on the underside of the thorax (prosternum) is bare, having no setae. The small plate between the thorax and abdomen (scutellum) has two pairs of long bristles, the forward pair (nearest the head) convergent, the rear pair divergent. The abdomen is no more than two times as long as wide. It is broadly connected to the thorax, not constricted at the base. The wings are clear. The small membranous lobe at the base of the forewing that covers the haltere (calypter) is well developed. The fourth segment (tibia) on the middle leg has just one bristle on the upperside before the tip (anterodorsal).

Glossary

Calypter

On flies: one of two small membranous lobes at the base of the forewing that covers the haltere. On mosses: A thin cap that covers and protects the capsule and operculum and drops off at maturity.

 

Halteres

In flies: a pair of knob-like structures on the thorax representing hind wings that are used for balance.

 

Scutellum

The exoskeletal plate covering the rearward (posterior) part of the middle segment of the thorax in some insects. In Coleoptera, Hemiptera, and Homoptera, the dorsal, often triangular plate behind the pronotum and between the bases of the front wings. In Diptera, the exoskeletal plate between the abdomen and the thorax.

 

Seta

A stiff, hair-like process on the outer surface of an organism. In Lepidoptera: A usually rigid bristle- or hair-like outgrowth used to sense touch. In mosses: The stalk supporting a spore-bearing capsule and supplying it with nutrients. Plural: setae.

 

Tibia

The fourth segment of an insect leg, after the femur and before the tarsus (foot). The fifth segment of a spider leg or palp.
