Crawford, 1914

Cacopsylla sinuata is a of , or 'jumping plant louse,' described by Crawford in 1914. Like other members of the Cacopsylla, it is a small, phloem-feeding hemipteran with siphon-like mouthparts. The species belongs to the Psyllidae within the suborder Sternorrhyncha, which includes other sap-sucking insects such as aphids, , and whiteflies. Specific ecological details for this species remain poorly documented.

Identification

Identification of Cacopsylla sinuata requires examination of morphological features typical of the : small body size (typically 2-5 mm), membranous wings held roof-like over the body, and siphon-like mouthparts. Distinction from congeneric depends on subtle characters of wing venation, genitalia, and body coloration. Accurate identification to species level generally requires taxonomic expertise and comparison with or authoritative keys.

Distribution

Distribution records indicate occurrence in western North America, with documented presence in Alberta (ABTOO), Alaska (ASKOO), Colorado (COLOO), Idaho (IDAOO), and Manitoba (MANOO).

Taxonomic note

The specific epithet 'sinuata' (Latin for 'wavy' or 'curved') may refer to a morphological feature of the wing margin or body outline, though the original description by Crawford (1914) should be consulted for confirmation.
