Necydalis from North Vietnam

Necydalis is very interesting genus of long horn beetles (Cerambycidae), very diversity in Indochina area. They belong to Lepturinae subfamily, some authors arrange them as a distinguish subfamily, Necydalinae. They are tiny beetles with a short elytron and the hyaline hind wings appear clearly so they look like wasps.

In nature, they are really perfect mimic beetles and under sun light, they look same to small wasps, not only the wings but also the abdomen. The reason for many kind of cerambicidae beetles "want to be" look like a wasp maybe because most of them are flower beetles, and wasp is a good subject around flower for mimicking, poisonous insects. So if you are not poisonous, you still can be an creature that look like poisonous, at least it helps you alive.

They are day flying insects and the best method to collect them is summit collecting during sunny days. With a big insect net, waiting at the top of mountains, above of the canopy of the tropical forests, collectors can catch them as they fly up with the wind. Because of small size and fast flying, they are not easy to be catch, particularly in a shining sunny day, they seem are invisible insects flying with hyaline hind wings.
