NOTES ON THE BIOLOGY AND MORPHOLOGY OF FALSE CLICK-BEETLE LARVAE (COLEOPTERA: EUCNEMIDAE)

摘要

The function of microtrichial patches and areoles found in most eucnemid larvae is discussed. The areoles are regarded to be water excreting organs important for larval water-balance. The microtrichial patches were known to be an essential part of the larval locomotory method. It is suggested the modified spiracular collars associated with larvae of certain Dirhagini and Macraulacinae play a similar role. This appears especially clear with respect to Asiocnemis spp. The overall similarity between soft-bodied larvae of the few true wood-boring Eucnemidae is considered a homoplastic adaptation to Multiple secondary invasions into relatively hard wood.
