Long-horn Beetle
Crossotus (?)
Observed attracted to electric lights at southern end of Kerio Valley, Kenya, Africa. December 2014. Length about 20mm.
Longhorn beetles are the adult stage of grubs that tunnel into dead twigs, branches or roots of trees and shrubs. Some species cut off the flow of tree sap into a twig by girdling it first. Adults lay eggs beneath the bark and the emerging grubs tunnel through the wood leaving a flattened oval gallery.
