Which of the following insects is closely related to powderpost beetles?

Powderpost beetles are closely related to termites due to their similar ecological niche and the wood-destroying habits they share. Both groups belong to the order Coleoptera, which includes beetles, and have specialized adaptations allowing them to thrive in wood. While powderpost beetles mainly target hard woods, termites primarily consume cellulose, which is found in all types of wood, making their interactions with wood similar yet distinct. This relationship emphasizes the importance of recognizing specific wood-destroying insects in pest management. The other insects listed do not share this close familial relationship in terms of wood consumption and structural damage, focusing instead on different behaviors and habitats.
