For some reason the national recorder for slugs thought I’d used a photo app to identify this slug, which I’ve never done. Maybe he just assumed everyone uses them these days, and, in this case, he was ‘afraid the photograph app which you have used has led you astray’. The truth is that I’d googled, and searched various online websites, and couldn’t work out what this slug was so had just recorded it as one of the Arion species. I even managed to get that wrong – turns out this is one of the Three-band slugs (though, I have to admit, I can only see two bands) and ‘At present we cannot tell which of the two species it is without dissection so it has to be recorded just as Ambigolimax‘. I’ll know for the future.

Disco for slugs

Who knew slugs liked disco? Lemon disco, that is. The fungus, not the John Travolta – Saturday Night Fever – Bee Gees – strobing lights type of disco. This particular slug certainly did, as it had paused its slithering to taste the delicate little yellow cups.

Deliquesce: verb; (of organic matter) become liquid, typically during decomposition. Mid 18th century from Latin deliquescere ‘dissolve’, from de- ‘down’ + liquescere ‘become liquid’ (Oxford Dictionary).

These Shaggy inkcaps (Coprinus comatus) may look sturdy and robust but, like all inkcaps and many other species of fungi, they only last a few days, sometimes as little as 24 hours, before turning into a rather disgusting-looking liquid mush, as shown by the specimen below. If you want to read more about the how and why of that process, about the inkcaps’ ‘habit of destroying themselves with their own enzymes’, check out The Dish on Deliquescence in Coprinus Species by Jonathan Landsman on the Cornell Mushroom blog.

Many humans may not know that inkcaps quickly deliquesce but slugs do. This slimy beastie was digging in to a Shaggy inkcap delicacy before the fungus had a chance to digest itself.

I know Wales has a reputation for being a wet country but the past couple of weeks have been much wetter than any I’ve known in my four years here. Still, it’s good weather for slugs, which is why this large and colourful beastie was to be found sliding its way across my path today. It was about 3 inches long and I presume, despite its colour – they vary a lot, that it’s a Black slug (Arion ater agg.), a species that can only be positively identified by examination of its genitals. I’m not going there!

Once the rain stopped this afternoon, I went out for a wander, looking to see if there were any new fungi after the dampness of recent days. What I found were shell-less terrestrial gastropod molluscs, big fat slippery slimy slugs that had at least partially devoured many of the tasty-to-them, newly sprouted mushrooms.

Isn’t it interesting that we use a lot of ‘slug’ idioms and expressions in the English language? If we are fighting, we are also slugging it out. If we’re working hard at a task, we’re slugging away at it. If we’re having a shot of alcohol, we’re having a slug of the drink. Well, today I saw many literal illustrations of the word sluggish: all those terrestrial gastropod molluscs, like the Leopard slug (Limax maximus) in my photos, were looking decidedly sluggish as they sleepily digested the hefty portions of fungi they’d consumed for their lunch.

In case you’re a gardener and think I should have killed this creature, this slug is actually one of the good guys. It won’t damage healthy living plants, preferring fungi, rotting plants and even other slugs, and it recycles nutrients, helping to fertilise the soil.
