Uninvited house guests


The rain might be lashing down outside but there's still plenty of wildlife to track down much closer to home. Unless your house is hermetically sealed and doused in deadly chemical cleaning agents, any or all of these could be lurking in the shadows.



If you settle down to read a good book and the punctuation seems to be moving around, then you could be looking at one of these tiny booklice. They are not much bigger that a full stop and feed on fungi that grow on damp paper, and also eat the glue that holds the pages together. Old damp paperbacks are prime habitat but they also like nothing better that feeding on wallpaper paste behind loose wallpaper. If your wallpaper makes clicking noises, it may be because they are headbutting it during their courtship.


Silverfish. You might have these most ancient of insects, that move like greased lightning, in a damp corner of a kitchen cupboard where they like to feed on starchy foods like flour.


Silverfish Lepisma saccharina are covered in tiny scales that rub-off easily, making it easier for them to wriggle out of the grip of a predator - which might go some way to explaining why they've been around for 400 million years.



This is the firebrat, the silverfish's larger and hairier cousin. It likes warmer conditions and used to be common in bakeries. Give yourself a pat on the back if you provide a home for these - they are not very common.



































And finally, the daddy long-legs spider Pholcus phalangioides. Whatever you do, don't throw these out of the house as they can't survive anywhere else. They are humans' constant companions, only ever found inside our homes and outbuildings in our northern latitudes. They are useful to have around, preying on other household invertebrates - even on the fearsome house spider that comes into our homes during cold weather. This daddy long-legs spider is showing her maternal instincts by carrying her eggs around in her jaws.

Insects in mid-winter


Still pretty mild for January - mild enough for these insects to be active:


Small.........


An unidentified fly feeding on winter flowering sweet box (Sarcococca confusa) this afternoon, carrying a lot of pollen on its hairy body. The books say that sweet box is highly scented - but not to me, I can't smell it. Maybe it's similar to the ability to smell Freesias - some can, some can't. Sweet box certainly attracts flies, though.

Smaller..........


Owl midges, about 3mm. long, on the surface of rainwater in a bucket in the garden. They are breeding in vast numbers in the compost bin during this mild weather - every time I open the lid swarms fly out and are fatally attracted to the water. For more on owl midges click here and here and here .

Smallest..................


A booklouse (psocid), less than 2mm. long, living in a bag of walnuts (imported from France) that we stored in our conservatory. For more about this unusual but very common little insect click here
