Trichodezia albovittata, the white-striped black moth, is a moth in the family Geometridae. It is found from Alaska to Newfoundland and Labrador, south in the east to North Carolina and in the west to northern California. [3] The wingspan is 20–25 mm. Adults are on wing from April to September. The larvae feed on Impatiens species.
The adult cottonwood borer is a large longhorn beetle with a black-and-white coloration and black antennae as long or longer than the body. [5] The white portions are due to microscopic masses of hair. [6] The larvae have legless, cylindrical, creamy-white bodies with a brown-to-black head and grow up to 38 millimetres (1.5 in) long.
June beetle larva stage. The grubs will grow to about 40 mm (1.6 in) and are white with a brownish-black head and brown spiracles along the sides of the body. The larvae will molt twice before winter. The fully grown larva color is glassy yellowish white shading toward green or blue at the head and tail.
Thin stripes of white are visible on the abdominal segments. [7] The wings of P. tibialis are brown in color with the brown emanating from a completely dark colored discal cell to outside the limits of the great cross vein. [13] The lateral areas of the head are light yellow, and the segment connecting each half of the face is black. [7]
The head and collar as well as the pectinations of the antennae are black. Tibiae and tarsi with broad black rings. The East-Asiatic species Leucoma candida (Staudinger, 1892) with different male genitalia structure, has much purer glossy white and entirely opaque, more thickly scaled, wings and is on the whole smaller, with narrower wings ...
Larval Sciaridae are slender and lack legs. They are white except for a black head, and their skin is slightly transparent so the contents of the gut are visible. [4] The abdominal creeping welts lack sclerotised spicules; this differentiates Sciaridae from the related family Mycetophilidae, in which sclerotised spicules are present. [6]
Abdominal tergites 3 and 4 have a marginal sulcus. The face lacks a black stripe, but has a black edge to the mouth. The frons in females has large dust patches.
