Hi Only,

These are indeed called 'leather jackets' or daddy longlegs larvae. they are just brilliant to use for freshwater fishing instead of worms. ive often caught up to 20 perch with just one leather jacket, the fish are not able to pull them off the hook cos of their tough skin.
if you do decide to make a killing on them for the anglers don't keep them in the fridge cos they go all hard an brittle and some might even die! no they need somewhere warm and damp like your bathroom. also if you do handle them don't squeeze too hard or they'l pop and then it gets messy.

glad to be of help

regards
