[rab] It's not unusual to see the odd 'peg leg' wandering around.

Which reminds me ...
At the risk of boring you to death. About six or seven years ago I was sitting in the 'bar' (actually the garage) of a mate's place and was positioned next to a largish double sliding glass door which gave access to the rear of the house. Whilst enjoying the afternoon sunlight beaming through the glass (that's the door, as well as the hand held one!) I noticed a wasp wandering up the pane. It was about 2" to 3" long and was dragging a huntsman spider up the door. I had heard of wasps paralysing spiders and laying their eggs within but had never seen the act. Anyway, interesting as that was at the time, some twelve months ago I had a wasp buzzing around in my workshop - it's not unusual and usually ignored - which finally got itself tangled in my hair (what's left of it.) Naturally I brushed it away. When I did it dropped its load; a load that I had not realized it was a'carrying. The bounty which it had lost landed on the keyboard of my computer which I was using at the time; it was the legless body of a huntsman! Urrgh! It turns out that the wasps paralyse the spiders, nibble off their legs at body level and then lay their eggs and secrete them within the little dirt cells that they build. It gave me the shivering quits for a couple of days, I can tell you.

[Duj] Thanks for that. I suddenly find that I can't face my Weetabix this morning.

[Dujon] I refer you to my previous remark.

[Dujon] That is possibly the most traumatic thing I have ever heard. Thank God that disgusting item didn't land IN YOUR HAIR. However, I was under the impression that the things that paralyse spiders and lay their eggs on them so that they get slowly devoured by grubs are not wasps but ichneumons, which look similar. Ordinary wasps, however, do carry body parts in the way you describe - I once watched a wasp attacking a bee, which it did by sitting on its back and systematically chewing through its thorax. When it finished it flew off with the abdomen - presumably the yummy bit - leaving the front half of the bee staggering around until I mercifully squashed it. Perhaps what you saw was the aftermath of a similar act of piracy. The mere existence of the ichneumon, by the way, was partly responsible for the Victorian "crisis of faith", because many found its existence impossibly to square with the notion of a good creator God. Incidentally, I will keep your anecdote for when I need to terrify my girlfriend. She refused to come to bed last night because a SMALL MOTH was sitting on the wall. Well, that's what she said anyway...

[Spiders] I see your spiders (*shudder*), and raise you The Japanese Spider Crab: The biggest crab is the Japanese Spider crab (Macrocheira kaempferi), which lives on the floor of the north Pacific Ocean; it has a 12 ft (3.7 m) leg span.
