Me likey. I think it would make a great D&D/fantasy (or even sci-fi or pulp/horror) type monster. Lose the wings, make it basically man-sized, with six motile limbs and a pair of appendages that vibrated extremely rapidly, (too fast for normal observation) that could both whip and stun, it would spit a liquid very much like naphtha or the chemical fire of a bombardier beetle, they would travel in hives of up to six with overlapping sensory fields and so would be able to organize concerted attacks, be well armored (they would have chitin) but extremely fast, and you'd have a really dangerous monster. they would have the ability to detect vibrations, hear extremely well, sense body-heat, and perhaps see in spectrums that humans could not sense. The proboscis and the stylets could be weapons, and it might secrete a paralyzing substance when attacking with the mandibles or mouth. And of course it might have a retractable stinger with a sufficient toxin load to kill a single man, maybe even a horse.
Plus they might even be able to be controlled by another creature by hypersonic vibrations, or maybe even sub-sonic vibrations, or able to produce their own sonic weaponry which would be amplified in their hive hunting pack, and so they'd be even more dangerous. Heck, the appendages might produce a vibratory hypersonic frequency, and an organ in the thorax or abdomen might produce a sub-sonic attack.
All in all this could be turned into a formidable monster at the man-sized level.
