Cerambyx welensii

For adult cerambyx welensii, a suitable trap might include sugary bait or fermented fruit to attract them since many Cerambycidae are known to feed on sap or decomposing vegetation.

The eggs of cerambyx welensii are commonly found in the crevices of tree bark, where they are laid by the females. Once hatched, the larvae reside inside the wood, boring extensive galleries as they feed and develop. To locate larvae, one would inspect the trunks of old, decaying trees, seeking out entry holes or sawdust-like frass. Pupation occurs within the wooden tunnels carved out by the larvae. Searching for pupae requires careful examination of the wood, often necessitating the removal of bark or cutting into the infested wood. The adult cerambyx welensii typically emerges from the wood and is often found on or near the host trees, particularly on the bark or foliage where they mate and the females lay their eggs, starting the cycle anew.

The most suitable time to find cerambyx welensii is likely during the warmer months when adults emerge for mating and when larvae are active inside the host plants.

Warm and dry conditions are typically suitable when searching for cerambyx welensii, as these are conditions that favor adult activity and larval development.
