The Xyelidae are a comparatively species-poor family of sawflies, comprising about 80 extant species in five genera worldwide, and is the only family in the superfamily Xyeloidea. [2][3] The fossil record of the family is extensive, comprising more than 120 species [4] and including the oldest fossil Hymenoptera species dating back to the Triass...

Xyela is a genus of sawflies, belonging to the family Xyelidae. [2] The genus was described in 1819 by Dalman. [2] The genus has cosmopolitan distribution. [3] Larvae of most species of Xyela live and feed in the developing staminate cones of Pinus (Pine) species. One species, gallicaulis, forms shoot galls.

2024年4月5日 · One flight per year, usually in spring, coinciding with development of staminate cones of pines. Larvae take 2‒3 weeks to develop, then drop to ground, construct earthen cells, and overwinter as prepupae (Burdick 1961 fide Greenbaum 1974)

The family Xyelidae are recognized by most phylogenies as the most primitive sawfly family (Ross 1932). The two subfamilies have two distinct host preferences, one for coniferous coniferous: ). The family can be easily recognized by the expanded first flagellomere flagellomere: ). Xyelidae includes 52 genera and 158 species worldwide.

Genus: Xyela Dalman, 1819 Subgenera: Xyela, Mesoxyela, Pinicolites. Background. Most phylogenies position Xyelidae as the most primitive family of all Hymenoptera. The xyelids are usually associated with a primitive plant group, coniferous coniferous: describing a conifer trees (Ross 1932, Blank and Kramp 2017 Blank and Kramp 2017: Blank SM and ...

2022年4月13日 · One new genus and two new species, described from new fossil specimens of northeastern China, enhance our knowledge of the Xyelidae in the mid-Mesozoic. A key to the genera of Angaridyelini and a table of known fossil species of Macroxyelinae are provided.

Xyela is the most diverse group of extant Xyelidae comprising 48 species worldwide including eight described here from Eurasia (Smith 1978, Taeger et al. 2010, present data). Xyela primarily occurs in the Holarctic, and like its host plants, pine species (Pinus spec., Pinaceae), it extends southwards into the northern parts of the Neotropical

The 28 Eurasian species of Xyela Dalman, 1819 are revised based on material of ca 7,500 imagines including about 10 % reared specimens. Larvae of Eurasian Xyela usually are monophagous and feed inside the staminate cones of pines (Pinus spp., Pinaceae).

Xyela minor is a species of sawfly in the genus Xyela that is endemic to North America. It can be found from Quebec to Florida, and west to British Columbia and California.
