There are several species of arthropods called “Daddy Long Legs”, including crane flies and harvestmen. So I prefer to call the spider version by its alternate name, the cellar spider. I’m always amazed by how they will tackle much bigger prey, like this house fly. The spider is just a young one, they do get quite a bit bigger. Their legs must be stronger than they look as you’d think they’d get broken by the struggles of their prey. Unlike the orb spiders, their web isn’t sticky, so it is quite a job to entangle their prey.
Another interesting fact is the way they spin around if you disturb their web, by moving their legs in turn so the body just becomes a circular blur, very hard for a bird to catch it in its beak.
A little more attractive to some is this collection of empty snail shells and a ladybug (ladybird in English) trapped by the intake to the filter of my upstairs aquarium.
