4. Biology
4.2 Hosts

Hosts of North American species of Xeris are summarized from Cameron (1965), Middlekauff (1960), Ries (1951), Smith (1979), and Schiff et al. (2012), and those of Eurasia by Spradberrry and Kirk (1978), Fukuda and Hijii (1997). In the list below we provide rearing records for nine species of Xeris from two families of conifers representing 12 genera and 36 species. The host cited is the plant on which the larvae actually fed or the female was found ovipositing. Plant species on which adults were found resting are not included. In the “Hosts” section under each species treated, we list the plant species attacked and, when possible, we add in parenthesis the number of specimens we recorded from a given host, or published records when we are confident of the accuracy of the identification.
