Which wax moth species poses the higher structural risk to woodenware components like hive walls?

Answer

Greater wax moth (Galleria mellonella)

While both the greater wax moth and the lesser wax moth consume beeswax comb, the greater wax moth (*G. mellonella*) is widely recognized as the more destructive of the two species generally encountered by beekeepers. A key differentiator in their impact relates to structural damage; the larvae of the greater wax moth are capable of spinning tough cocoons cemented directly into the wooden components of the hive structure itself. This behavior results in permanent physical damage to woodenware, a level of structural destruction that the lesser wax moth larvae, which are reportedly not found in actively occupied comb, do not inflict to the same extent.
