List of largest insects
The largest wasp is probably the so-called tarantula hawk species "Pepsis pulszkyi", at up to long and wingspan, although many other "Pepsis" species approach a similar size. The giant scoliid wasp "Megascolia procer" may rival the tarantula hawks in weight, if not length and wingspan, and the Asian giant hornet "Vespa mandarinia" can reach a body length of up to 2 in.
