Tomoxia Costa, 1854

Tomoxia bucephala Costa, 1854

This adventive species from the western Palearctic has been newly reported in the northeastern United States ( Naczi et al. 2022). Adults feed on fungal spores and females oviposit into cracks on the bark or in tunnels created by other insects. Larvae bore through fungus-infested wood (more detailed life history reviewed in Naczi et al. 2022).

Tomoxia inclusa LeConte, 1862

This species was observed emerging from a dead basswood in Ontario ( Brimley 1951). Adults also were collected from a recently cut spruce log in New Brunswick (Webster et al. 2012) and beaten from dead hardwood limbs (Downie and Arnett 1996).

Tomoxia lineella LeConte, 1862

Adults were collected from dead hardwood trees, such as elm, basswood, ash ( Fraxinus L.; Oleaceae ), beech, and hickory ( Felt 1924; Liljeblad 1945). Additionally, it was found in association with dead sugar maple ( Acer saccharum Marshall ) in Indiana (Downie and Arnett 1996) and beaten from the limbs of a dead, hard maple in Ontario ( Brimley 1951). In Wisconsin, mature larvae were collected from tunnels inside a standing dead large-tooth aspen ( Populus grandidentata Michx. ; Salicaceae ) in late March, and adults emerged from collected material 33 days later (Lisberg and Young 2003a). The tunnels were roughly 2 cm beneath the bark with the surrounding wood still hard (Lisberg and Young 2003a).
