Recognize the Asian long-horned beetle and its symtoms

Are the larvae recognizable?

Females of the Alb lay eggs only in living wood. The larvae dig galleries into the wood (wood borers), are creamy white, without legs, with brown front chest, up to 5cm long when fully developped.
Larvae complete development has been recorded both on living and dead trees. The larvae are however hard to distinguish from those of other big size beetles. For example white larvae, that can be observed in the soil or in the wood dead since more than 2 years, are not larvae of ALB but probably of native non-harmful beetles.
