Chionea scita

[5] Both sexes are yellow-brown in color and are similar in size; however, sexual dimorphism is observed with respect to elements of external genitalia as well as femora length.

[7] C. scita are native to North America and are commonly seen in the northeast United States, as well as parts of Canada.

[3] C. scita adults are yellow-brown in color with long, thin bodies and prolonged delicate legs.

[13] Female cerci are light brown, uniformly curved and are less elongated compared to other species of Chionea.

[7] The female has a genital furca with two extending arms which deviate from the basal plate and eventually curve to join the 9th sternum.

[6] There may be an association between the nesting sites of small mammals and the appearance of C. scita but this connection requires further study.

[6] C. scita males have a uniformly curved penis with a sclerotized region located on the ventral side.

C. scita females have three separate spermathecae chambers, which are structures found in many Dipterans that store sperm after copulation has occurred.

Since adult C. scita are wingless, they also lack these bulky muscle structures, which allows females to carry many eggs at a time.

Little research has been done on the process of oviposition in C. scita, however females generally lay eggs after they emerge in the winter months, usually after a snow fall when temperatures are between 28 °F and 38 °F.

Francis Walker identified and named Chionea scita in 1848.
