Xylotrechus quadrimaculatus (Haldeman) View in CoL . New
larval host records.
Larvae of this species girdle living branches of various hardwoods, mainly Betula spp. (Betulaceae) and Fagus grandifolia Ehrh. (Fagaceae) ( Craighead 1923). Branches that break off and fall onto the ground retain leaves and can be readily seen on the forest floor. Infested branches can be collected during summer and throughout winter. The beetles emerge the following spring.
In the Poconos region of eastern Pennsylvania, JV frequently found larvae in Betula lenta L. and Betula alleghaniensis Britton. JValso reared it from additional new host plants: Betula papyrifera Marshall and Alnus incana (L.) Moench from NY: Franklin Co., Tupper Lake; Ostrya virginiana (Mill.) K. Koch (Betulaceae) from NY: Oswego Co., Pulaski; and Corylus cornuta Marshall and C. americana from PA: Luzerne Co., Nescopeck Creek.
