Bugman jones the life and times of a curious entomologist cirugia lumbar

First cut a rectangular hole in the top using a naked ‘safety’ razor blade (a Stanley knife might have been available later). Wooden matchboxes, back in the day, were easier fisioterapia lumbar to cut than the cardboard ones. Next glue a cover of clear cellophane over the window using that gaggingly smelly animal glue boiled up in a home-made bain-marie on the gas ring. Finally give it a neat paint job, and a number.

For at least my first decade these were our collecting boxes of choice. They were ideal for the sorts of creatures we were finding — hoverflies, greenbottles, weevils, leaf beetles, longhorns, moths, water boatmen, shieldbugs, grasshoppers and caddis flies. Anything rotoescoliosis lumbar too small could often squeeze out of a gap.


Sometimes a large solitary wasp would chew a hole in the corner and escape.

I was probably 13 or 14 when I made the change to glass tubes, and although Dad did too, he often also carried a few of these old boxes in case he found a particularly large water beetle or a big fluffy moth. He’d then make an entry in his field notebook, of the painted number on the back, what he’d found, and where.

During the last 10 years of his life he hardly collected any insects, he spent all his fieldwork hours recording plants. But when I’d visit he’d pull out some of the latest things he had found and was struggling with. They were all small fry — the sort of thing you could only put into a small glass tube, not a loosely fitting matchbox. But he still kept these, along with a few similarly painted tobacco tins of uncertain provenance. Just in case.

It’s not escoliosis de convexidad derecha just insects, or wildlife, or even nature that fascinates me. It’s everything about the world — and the universe beyond it. I’m embarrassed to say that it’s dimmed a bit of late, but when I was a boy I was deeply interested in astronomy. I had an Airfix model of a Saturn V rocket, planetary and star charts on the wall, and a map of the moon marked with Apollo and other landings.

But it was an astronomy picture book I sent off for, from the back of a Weetabix packet (or it might have been Shreddies) when I was about contractura lumbar izquierda 10, that caused all the trouble. It haunts me to this day. In it was a diagram showing the life of a typical star, from vague gas cloud to condensed solar orb of the main sequence (like our sun today) to red giant to white dwarf. It was a simple diagram, clear and to the point. It was this that got me all agitated.

Five billion years from now, having used up nearly all of its hydrogen in fusion to create helium, the sun’s mass (currently 2 x 10 30 kg) will have reduced to the point where escoliosis dolor its gravity grows less, the internal pull on its gaseous structure diminishes and it starts to expand in size. As the outer layers glow hotter and redder, it will engulf the orbits of, first Mercury, then Venus, then Earth.

I was beside myself with despair and sat on the bed weeping and wailing my 10-year-old equivalent of “What’s the point of it? We’re all going to die.” It wasn’t so much my own death I was worried about, more the end of civilization as we know it.

My father sat down on the bed to try and console me. He probably tried to explain why it didn’t matter what would happen 5,000,000,000 years from now — further into the future than the Earth is now from its origin. Maybe he made science-fiction predictions about operacion hernia discal lumbar translocating the Earth’s population to extraterrestrial colonies, or perhaps even towing the planet off into deeper space.

• No spiders are poisonous — they are venomous, that is how they catch their insect prey. Expansion note: Stinging nettles are not poisonous, cook them and they are delicious (taste like spinach), but they are venomous and sting by injecting venom through tiny hollow hairs on the leaves and stems.

• Humans are covered in an amazing substance called skin, even in children it is too thick and tough and leathery for most spiders to get escoliosis de convexidad izquierda their fangs into; spiders have small mouths and just cannot get their jaws open wide enough to give a nip. Expansion note: Imagine you are a spider trying to bite a human finger — it’s like you trying to take a bite out of a big leather football. Skin is also waterproof — try cleaning it with soap in the bath.

• Of roughly 670 different species of spider in the British Isles, only about 6 species have fangs long and strong enough to get the venom through. It feels a bit like a bee sting. Expansion note: Imagine you are a school teacher and see bees visiting flowers in the playground; do you close the school because of a dangerous threat? No, obviously not, that would be silly.

• Spiders are small, solitary and non-aggressive, they have soft delicate bodies and do not want to get into stand-offs or fights with humans. Expansion note rotoescoliosis dorsolumbar: If you pick up a spider between finger and thumb it might try and fight back by biting. If you pick up a bee or wasp between finger and thumb it will sting you. If you pick me up between finger and thumb I will bite hernia lumbar l4 l5 and kick. Children are more likely to be bitten by each other than by spiders.

• No school, office, home or indeed any building should be closed because of an ‘infestation’ of spiders. Expansion note: If you are worried about spiders ask to speak to one of Ivydale School’s pupil arachno-ambassadors, they’ll put you straight.

The gypsy moth, Lymantria dispar, was once native to Britain, more or less limited to East Anglia, but had disappeared after the widespread draining of the fens during the 18th and 19th centuries. When it re-established itself in the London area at the end of the 1990s there was a flurry of activity trying to control what could potentially be a major forestry pest. In some parts of Europe, and in North America (where it was deliberately released dolor lumbar bajo during the 19th century for a putative domestic silk industry), it can cause defoliation of large swathes of trees.

The moth, however, seems to be well-esconced here, and eradication plans have subsided. When I found an adult moth in the Olympic Park near Stratford a few years ago there was some mild consternation from the park authorities, but there is precious little anyone can do unless the gregarious caterpillars can be found early enough and the whole nest of them cut out and destroyed.

I’m not sure where my singleton on the peony came from. There are several very large pear trees in neighbouring gardens and we’ve got an apple. I’ll have a closer look escoliosis toracolumbar over the next few days. The only time I ever saw the caterpillars before, they were feeding on oak trees at the London Wildlife Trust nature reserve at Gunnersbury Triangle. Here they were creating escoliosis lumbar sintomas their characteristic silk trails up and down the trunks, moving upwards in procession to feed on the leaves during the night, but returning, following the silk lines down, to huddle in a great knot on the bark during the day.

There has also been a spate of recent sightings of the oak processionary moth, Thaumetopoea processionea, in London. Like the gypsy moth it appears to have colonized Britain very recently, and its caterpillars also move in long lines, follow-my-leader style, but only on oak trees. Again, there has been some activity to try and get the public to report outbreaks so that they can be located and destroyed. I’ve just had a notice of work going on in Catford. Concern is centred on possible tree damage, but also on the caterpillars’ long brittle hairs which contain a venom and which can cause escoliosis lumbar consecuencias irritation in some people. There is a risk of rashes if the caterpillars are handled, or of eye-irritation or asthmatic breathing difficulties since the hairs break and fragments float in the air.

London has a long history of ‘dangerous’ caterpillars, ever since the serious 18th and 19th century outbreaks of browntail moth, Euproctis chrysorrhoea, caused the local beadle to offer a bounty of 6d per bushel for their silk-strand nests cut from the orchards of Clapham and Battersea. There was a massive bonfire to destroy them. Every so often there is a plaintive warning about the stinging browntail caterpillars from various London borough councils, and warningly titled information sheets are circulated.

I can be fairly blasé about browntails since I seem to be able to handle the larvae with impunity. But my sister suffered many years of tearful eye complaints because she lives on the south coast dolor lumbar embarazo primer trimestre where the moths and their caterpillars are always common. I’ll expect to come across more oak processionary and gypsy moth caterpillars, and will handle them cautiously when I do.
