Clearwing Moth

Description:

Black with a dark blue reflection to the wings. Front wing pair shorter than rear wing pair. Front wing scaled like a moth, rear wing clear and heavily veined. Antennae slightly curved outwards, just shorter than body length. Approximate length just over an inch.

Habitat:

Adjacent to a small stream. Altitude 1000m.

Notes:

At first sight it looked very like a wasp in its appearance and behavior. It waggled its abdomen rapidly up and down, as a wasp does when hunting for prey. The scaled wing gave it away as a moth and the rear clear wing venation led me towards melittia, but with stark differences.

I don’t remember seeing this one before and could not find it in a search.

Any ideas?
