Searching for the larvae would entail examining these specific tree regions, particularly looking for boreholes or sawdust-like frass that indicates their presence. The adults, on the other hand, are frequently found on the bark of host trees or nearby vegetation. To locate adults, one might explore the same environments as the larvae, paying close attention to the tree trunks and branches during their active period, which often is around late spring to summer.
