Why the daddy longlegs is a friend to housework-shy humans

Our reactions go back to our evolutionary ‘fight or flight’ response. When we are under threat, our brain floods our body with the stress hormone adrenaline signalling to our muscles prepare to either run away or stay and fight. It’s estimated that about four per cent of us fear spiders, and as a phobia, it comes second only to snakes. If we are truly phobic it means that we are fearful to the point of irrationality, and the terror we experience far outweighs the actual danger posed by the object of the fear.

If you are worried about house spiders then I suggest you rein in your instinct to clean because they have a natural predator that loves nothing more than setting up home in the corner of your living room. The trouble is though (especially for arachnophobes), this helpful predator is yet another spider. In its defence it’s much less scary and, unlike the house spider, does not whizz alarmingly across your floor at the rate of half a metre a second.

This creature is a friend to all housework-shy humans, a regular resident of neglected corners, cupboards and attics and a weird-shaped spindly thing, the lazy old daddy longlegs. Compared to the clean and ordered webs built by swotty old regular spiders, the slovenly daddy longlegs’ home is a shambles and described as ‘untidy’ and ‘without great design’ by the Natural History Museum. I can relate to that, because it reminds me of my side of my dishevelled university room compared to that of my unnaturally tidy roommate.

The light brown DLL (how I will refer to the daddy longlegs from now on because it is too much effort to type it out fully) is characterised by its long dark two-part body of abdomen and paler thorax (head end) to which are attached its eight ridiculously long skinny legs. It originated in the Sub-Tropics and after hitching a lift on an England-bound boat, was first documented in the south of the UK in 1864. Once it worked out that to survive our much chillier climate it had to stay indoors, it dared to venture up north and is now common all over the country.

It relies on its web to do the heavy lifting where dinner is concerned, but if that fails, it will get off its idle backside to hunt food, which includes - arachnophobes take note - other spiders. In the entomological version of analysing the rubbish left outside MacDonalds, someone in Hampshire decided to count all the food waste discarded by the slothful DLL in the webs found in his garden shed. He discovered that of the 102 bits of leftover critter, 63 belonged to house spiders, six were DLLs, and the rest were mainly other spiders. How the DLL loves a spider-flavoured meal, even if it is their own sister.

There are a couple of other minibeasts that we also refer to as ‘daddy longlegs’, but they are distinctly different. You will likely have seen the harvestman in your garden, which from a distance looks very much like our DLL but is not actually a spider. Found outside among vegetation rather than indoors in webs, it has a teeny tiny bulbous single body and six long wispy legs. The other is the crane fly, that lanky-legged winged thing that looks like a giant mosquito and has a habit of bobbing into your room late at night to flap annoyingly round your lampshade. It may be the most stupid of creatures but its (literal) saving grace is that if it gets trapped by its dangly legs, they simply pop off and it bobs away again, unperturbed by the fact it is a leg or two lighter.

In conclusion, if you hate house spiders but can cope with the odd messy web of the slothful DLL, then perhaps you should welcome it into your home as your ally rather than your enemy.

But my educational takeaway from this column is that I now have a valid excuse to do even less dusting than I do already.
