one of the largest living insects?

If you don't like spiders then you probably wouldn't like this either: from China come reports of what's claimed to be the largest known aquatic insect. (I can't find any actual published scientific descriptions of the creature; it will be nice to see the claim confirmed - or denied! - as it's a pretty impressive specimen.

My first thought on seeing this image was, a dobsonfly! I've not ever seen an adult specimen, but the aquatic larvae I encountered when running a macroinvertebrate lab class (way back in my Massey days) have equally impressive mandibles - hence the nickname of 'toe biters'. Given that the adult Megalopteran pictured here has a 21cm wingspan (!), I wouldn't care to encounter its larvae when paddling in a stream.

Becky Crew has a great take on this creature on her Running Ponies blog, including some fascinating info on other giants of the insect world.

Hey There, Not So Little Insect!

They end up with enormous tusk-like mandibles and mouthparts as adults, [...] so the males use them to attract females
Works for me too.
