This is not an earwig of any

This is not an earwig of any species, but a larval insect (possibly a beetle, but equally perhaps another order).

Not an earwig...

An earwig would have short wing cases - looks like two of us were typing at the same time...

Earwigs and beetles.

This is the second thread with analmost identical insect that has initially been identified as an Earwig, the other was In general terms I can see why these conclusion has been reached - the two "tails" at the end could appear to be the "pinchers" that are typical of an earwig.

The problem with experienced people producing keys or ID guides for beginners is that it is often quite difficult to put down clearly on paper what appears "obvious" to the "experienced" eye. I would guess that the ID material being used here may not describe the key features well enough for a beginner to understand the "real" differences separating earwigs from beetle larvae.

It would be interesting to know what ID tools or keys were used to get to the initial identity for both this beastie and the previous posting. I can tell it's not an earwig by looking, but that is purely down to experience. Finding out where a key goes "wrong", particualrly if it is aimed at novice users, is an important way of improving the reliability of such keys, particularly if both original posters used the same key.

Earwigs and beetles

Oops! The baysian system produced a number of options of which earwig was closest, fossiking about on Google images suggested the option chosen. Being a novice is not easy.

Baysian system?

What is a "baysian system" - is it some sort of on-line key you are using for the course?. If so - do you have a link?

Hi Matt, The bayesian key is

Hi Matt,
The bayesian key is part of the iSpot website. You will find it at the bottom of the Useful Links "Species Identification Keys". It was recommended by the Open University 'Neighbourhood Nature' course. The address is:
You caught me on the wasp too. We can't go on meeting like this.
