Behaviour

Alfred Russell Wallace, in his book The Malay Archipelago, described the movement of these beetles as sluggish (he referred to Euchirus longimanus from Ceram, another long-legged species in the Euchirinae subfamily) and stated that they “drag themselves lazily along by means of their immense forelegs”.
The adult Cheirotonus parryi fly well and are often attracted to bright lights at night. This is often the best place to observe these otherwise secretive beetles. The adults feed on tree sap and fermenting fruit and are known to gather on sapping trees together with other insects.
