Could this not be a leech? I get them from time to time in my outside containers/ponds, horrid things, but I like your mayfly nymph, how long before it becomes a fly, bit late in the year isn't it? Will it overwinter then?

[Vale!]

Oh - good call, SL!

I bet that's exactly what they are. That would explain why I couldn't see a ... that ring thing that goes round about a third of the way down ... *looks up Google* ... clitellum ; and why the front end looks odd.

I shall extract them and any others I can find. Urgh!

Yes - I expect Morris will overwinter OK.

Seen at 'lights on' just now : blackworms with a death wish?





Maybe they think they're frogs! I hope they have the good sense to move before they poach themselves.

Poached Blackworms ...serve with chips and peas.

You do realise you will now have to keep the updates coming on wee morris - you have named him now so he becomes part of the family

Looks like moths do with lights....

Looks like moths do with lights....

Chap called Anton Petrov ("Hello, Wonderful Person"!) runs one of my favourite Youtube channels - he digests technical papers across a spectrum of sciencey topics and presents them in a form that's (usually) vaguely understandable to the likes of us. Occasionally he mentions fishy stuff but so rarely that it's probably not worth adding to your subscriptions unless you've a general interest in science. Anyway ...

Earlier this year he considered a paper that explains why moths circle around lights : they think that they're flying in a straight line! Apparently it's because of a thing called 'dorsal ray perception' (I believe I've remembered that correctly - I'd have to go back and check) whereby they orientate themselves with respect to a light source such that it's always above their back. I'll see if I can find it quickly ... yes : https://www.youtube.com/watch?v=MzLe0Zk31_U - about twelve minutes long.

My radar is mow fully honed in on this thread @Vale! . Thanks for the link for mr Petrov’s channel. I would be very interested in such material.

That is a neat theory regarding the moths.

[plankton]

That is very interesting!
Backing off in straight lines (or trying to) would be something most would never work out.....

Ok then, let's go for "looks like cats do with fires" and see if that turns anything up.

@plankton

As a starting point I would refer you to an article by D.R. Kenshalo published in The Journal Of Physiology in August of 1964 (volume 172, no.3, pp. 439-448). The author's
summary carries the following two points

2) ... it is concluded that cats do not sense mild temperature increases on their furred skin.

3) It is concluded that cats are able to sense mild temperature decreases before the temperature decreases become noxious.


Next?
