ID : Limacidae slug species.

[Andrew C]

Hello,

This slug species was discovered whilst lifting logs as usual in Ashclyst Forest in Devon. I have had a look through the images on the BioImages website and the closest available structural match is Limax cinereoniger but this is a different colour altogether.

Can anyone advise me on the identification of this specimen. I apologise for the poor images as I had only my compact with me.

Regards,
Andrew.

Evening,

Would the attached image of a slug species seen in Stanniclift Copse near Doddiscombsleigh (Devon) be another Lehmannia marginata?

It was discovered under a log.

Regards,
Andrew.

Evening...

Looks good for Limax cinereoniger on new post/pic, this will be our largest slug. They can be quite variable in colour and pattern.

The first pic i'm not really sure on, but i think this is also Limax cinereoniger. The overall appearance and its keel seem to be more robust than that of Lehmannia marginata.

Limax cinereoniger is mainly restricted to woodland, it can be an indicator of "ancient woodland". It will also be worth keeping a look out for the very local Malacolimax tenellus, they are another old woodland species that can be found with Limax cinereoniger. These can be fairly hard to find. Though, they do love to feed on fungi (especially Russula sp), so a good look around and on these fungi should help in locating them...if they are there of course.

Regards Chris...

Evening Chris,

Thanks for the correction and explanation. The woodlands that both were found in are indeed ancient woodlands with other indicator species so that argues well for Limax cinereoniger possibly.

I shall look out for the other species on the fungi from now on!

Regards,
Andrew.

You will also find Lehmannia marginata in woodland as well as other habitats, they will be a smaller more watery translucent looking slug. They also vary in colour, mostly they will be grey-brown with two lateral bands on mantle and tail, yellow-grey with dark blotches or just a plain grey colour without any other markings.

Excellent, I shall keep an eye out for more 'ridge backs' under stones and logs.

Cheers,
Andrew.
