Cacopsylla nana

(Tuthill, 1938)

Cacopsylla nana is a of jumping plant louse () in the Psyllidae, first described by Tuthill in 1938. Like other members of the Cacopsylla, it is a phloem-feeding hemipteran that feeds on plant sap. The species is part of a large genus containing many economically important pests, though specific information about C. nana's and remains limited. It belongs to the suborder Sternorrhyncha, which includes other sap-feeding insects such as aphids, whiteflies, and scale insects.

Identification

Cacopsylla nana can be distinguished from other Cacopsylla by morphological features established in Tuthill's 1938 description, though specific diagnostic characters are not readily available in the provided sources. Members of the Cacopsylla are generally small (2-5 mm), with membranous wings held roof-like over the body, and possess the characteristic jumping ability that gives psyllids their . Accurate identification to species level typically requires examination of genitalia and other microscopic features by a .

Distribution

Distribution records indicate 79 occurrence records with ARIOO designation, suggesting documented presence in specific regions, though precise geographic range details are not specified in available sources. The Cacopsylla has a global distribution with many in the Northern Hemisphere.

More Details

Taxonomic Context

Cacopsylla nana was described by Tuthill in 1938. The Cacopsylla is one of the largest genera of psyllids, containing numerous many of which are significant agricultural pests. The genus has undergone taxonomic revision, with many species formerly placed in Psylla now classified in Cacopsylla.

Research Methodology Relevance

Recent advances in gut content analysis using high-throughput sequencing, as demonstrated with congeneric like C. pyricola, provide a novel approach to tracking landscape movements of phloem-feeding psyllids. This methodology could potentially be applied to understand the and non-crop associations of C. nana, which currently remain poorly documented.
