The social insects - bees, wasps, ants, termites - are frequently found trapped in amber resins, often in large groups or clusters. Although this specimen in Dominican amber closely resembles a winged ant at first look, it is in fact a very small parasitic wasp (probably Family Braconidae). The long, threadlike antennae and the lack of an obvious costal cell on the front wing margin are among characteristic features that quickly distinguish braconid wasps from winged ants.
This hawkmoth has been parasitized by an Akanthomyces fungus, a Cordyceps anamorph peculiar to moths (ID courtesy of tsanjuan) until it caused it's demise (seemingly during a normal resting period) and totally consuming and mummifying the corpse. Pu'er, Yunnan, China
