Pachyta lamed is a Holarctic long-horned beetle (Cerambycidae) in the Lepturinae. The occurs across northern Eurasia and North America, with two recognized : P. lamed lamed (Eurasian) and P. lamed liturata (North American). are associated with coniferous trees, particularly spruce. Larvae develop in dead or decaying conifer wood, completing development over multiple years.
