# Sphaerophoria

Sphaerophoria is a genus of hoverflies.
Species slender 5.6-12mm long with extremely large hemispherical male terminalia, after which the common name globetail was created (see gallery). There are bright yellow markings on head and thorax and usually on the abdomen but some species have a black abdomen. They can be found worldwide but are common in North America, Europe, Asia and Australia. There are over 73 described species.
The larvae--when known--are aphidophagous.

## Diagnostics

For terminology see Speight key to genera and glossary The male has a yellow frons, rarely with a pair of black spots above the antennae, while the female has a median black stripe. The face is usually yellow, often with black markings, and has a prominent tubercle that only recedes slightly to the lower facial margin. The eyes are bare. The scutum is glossy black with a wide yellow stripe that either terminates at the transverse suture or extends to the scutellum. The pleura have black coloring with bright yellow patterns. The anterior anepisternum is bare. The upper and lower katepisternal hair patches are distinct from each other, with the former usually extending ventrally in a triangular shape about three-quarters of the distance from the upper to lower margin of the sclerite. The meron and metapleuron are both devoid of hair, and the metasternum has some. There are small bare areas on the basal one-third of the wing membrane.
Males have an abdomen is that is slender, unmargined, and parallel-sided or slightly constricted near the middle. The fifth segment on the right side has a bluntly rounded posterior extension. Females have an abdomen that is parallel or slightly widened in the middle.
Male genitalia
The epandrium is typically very large, almost as wide as segment 5 and usually slightly longer than wide, with the posterior being slightly wider. The cerci are usually enclosed in a sclerotized layer of the epandrium. The surstylus is usually detailed and divided into three lobes. The dorsal lobe is slightly swollen at the top, round, and has a thick mass of long, coarse yellow hairs. The ventral lobe is flattened, sometimes elongate, and often split into two parts at the tip, with sparsely-haired but a densely setulose longitudinal ridge on its inner side.
