HOUSE FLIES (Musca Domestica)

This illustration shews why House Flies are one of the nastiest and most dangerous of pests. When feeding on meat, bread, or sugar they eject a liquid to dissolve the food before sucking it up.

The common House Fly (Musca Domestica) is barely a quarter of an inch tall, and measures from nose to tail less than three-eighths of an inch: its compact form is a model for Nature's most effective germ-dispensing mechanism.

Attached to its hairy body and stick-padded feet are germs of the widest range of diseases, including Amoebic dysentery, Bubonic plague, Gangrene, Leprosy, Tuberculosis, and Typhoid fever. The average number of germs found on a Fly's body is around 1,250,000 and can reach as high as 6,600,000.

The Fly is not affected by any of the germs it carries, it seems immune to them all.

During every 60 seconds a House Fly is in the air, its wings beat almost 20,000 times. In each wing-beat the Fly moves its two veined and transparent supporting surfaces in an intricate evolution - the tips move through the air in a series of figure eights, an entirely different form of wing-beat from a bird which remains aloft with fluttering or rowing motions. About eleven per cent of a Housefly's body is composed of the powerful motor muscles that operate its wings allowing it to travel at about 5 miles per hour.

One reasons a Fly, whether on the wing or at rest, is so hard to hit is the nature of its eyes. Humans have two lenses - one in each eye, the Housefly has eight thousand lenses - four thousand in each eye. Bulging outward from the sides of its head, the thousands of six-sided lenses fit together like honeycomb cells, and provide wide-angle vision unknown to humans; because the Fly has no eyelids it sleeps with its eyes open.

The House Fly has four life stages - egg, larva, pupa, and adult. the larvae crawl away from light, whereas the the adult House Fly is attracted to it, the male Housefly is more strongly attracted than the female. However, the females who use their sense of smell to find the best places for laying eggs, have a keener response to odors. Their smelling equipment is not a nose - it is a pair of stick-like feelers thrust out from between the eyes. Olfactory pits on these feelers enable the Houselies to catch faint odors not noticeable to the human nose.

Descending from the bottom of a House Fly's face is a proboscis, or sucking tube, ending in soft, fleshy mouthparts, this is its feeding equipment. It cannot bite because it has nothing with which to bite. It possesses no piercing beak or cewing jaws, it consumes only liquids. If a "Housefly" bites you , it isn't a Housefly, it is probably a Stable Fly that has come into the premises; these pests often come indoors before a rain shower, giving rise to an old belief about House Flies biting before a storm.

The fact that House Flies are on a permanent liquid diet increases their menace. When a Housefly lands on a food or other matter, it has to transform the solids into liquids. To do this it regurgitates some of the liquids already swallowed, together with its germ-laden saliva and waits until the surface is softened and liquified, it then reswallows the liquid leaving behind innumerable microbes.

The pads on a House Fly's feet consist of many short hairs exuding an adhesive substance to keep it from falling when it lands on a wall or ceiling. These pads are highly effective germ traps. Whenever a House Fly pulls away from a microbe-laden surface innumerable minute organisms come with it. Later, when the feet are set down again, the bacteria are deposited and left behind.

Let a House Fly walk across a dish of unsweetened gelatin and set it away for a couple of days and you will find the trail of its wandering shewing up as a whitish mold. The bacteria left behind have multiplied on the gelatin and are now visible to the naked eye.

Throughout its life the House Fly is associated with bacteria and filth, the eggs of the female, about 600 in all, are laid in batches of from 100 to 120. Sunshine stimulates breeding activity, and eggs develop with amazing rapidity. Often only 8 hours elapse before they hatch into larvae, wedge shaped, almost transparent, legless, and virtually headless. These larvae feed on the products of decay, shed their skins several times, and reach full size - about three eighths of an inch - in five or six days. During this time the maggot seeks the warmest spot it can find.

When feeding days are over, the larva retreats to a cooler place, its skin hardens , turns red , its body contracts, it becomes a pupa. Within this pupa the tissues are being re-formed into an intricate, winged and legged body; this transformation takes four or five days. After getting its wings the skin is shed and the adult Housefly emerges and grows no more. The smaller Flies sometimes seen are not "Little House Flies" - they are usually adults of another species, (Fannia Canicularis).

The complete lifecycle of the House Fly, from egg to emergence of the adult, lasts only a couple of weeks. As many as fourteen generations may follow each other in the course of a single summer.

Throughout its life the House Fly is associated with bacteria and filth, and effective Housefly control includes good sanitation and cleanliness. This is especially true in food preparation and serving areas.

A BEES-EYE VIEW : How insects see flowers very differently to us

By MICHAEL HANLON

To the human eye, a garden in bloom is a riot of colour. Flowers jostle for our attention, utilising just about every colour of the rainbow.

But of course, it is not our attention they need to attract, but that of insects, the perfect pollinating agents.

And as these remarkable pictures show, there is more to many flowers than meets the eye - the human eye at least. Many species, including bees, can see a broader spectrum of light than we can, opening up a whole new world.

The images, taken by Norwegian scientist-cameraman Bjorn Roslett, present a series of flowers in both natural and ultraviolet light, revealing an insect's eye view.



Evening primrose (Oenothera biennis): To the human eye the flower looks solid yellow but insects can aim for the bullseye in the centre



Dandelion (Taraxacum officinale): The familiar mop top is transformed for the bees


Ultraviolet light, invisible to us, uncovers colours and patterns which drawthem to the source of pollen and nectar - all hidden to humans without special equipment.

This secret colour world was discovered in the Fifties and scientists realised that these distinct patterns were designed to act as "landing strips" or arrows, guiding the insects to the right spot.

Because we cannot see UV light, the colours in these photographs are representational, but the patterns are real.

Wood anemone (Anemone nemorosa): Insects are often drawn to darker colours, so this vibrant hue would be instantly attractive and draw them in



Spring crocus (Crocus vernus): The ultraviolet image creates three rings of colour to guide insects to a happy landing



Silverweed (Potentilla anserina): It is hard to imagine that these yellow flowers are actually hiding a two-tone pattern, as revealed in the ultraviolet image



Many species, including bees, can see a broader spectrum of light than we can!

10 personality traits of a highly effective independent consultant

#1: Confident

You have to look at a challenge and say, “I could do that.” It might even help if you are a little megalomaniacal about your thinking; for example: “I can do anything, given enough time and information.” Now that we live in an era in which information is almost always only a google away, the question becomes, “Do I have enough time to master this?” Most of the spectacular failures of consulting engagements probably result from a false positive answer to that question — stemming from the very hubris that makes it possible to be successful.

#2: Problem solver

You need to be passionate about solving problems, because that is what you’ll be doing all day. Whether it’s a problem with computers, logistics, or personnel, your clients want you to solve it. Consulting may be for you if you like math and word problems; find problems in daily life more of a challenge in optimization than a drag; and enjoy playing a difficult game or solving a tough puzzle.

#3: Motivated

You have to be able to keep yourself on task, especially if you work from a remote office. If you can’t control your tendency to procrastinate, you’ll never get anything done — and if you never get anything done, you won’t keep your clients.

#4: Obsessive

Many of the problems you encounter will take a lot of mental juice to solve, which means that you need to be able to focus your attention for long periods of time. You also need to be able to continue to process a problem in the background when you’re not giving it full attention. Some of my best solutions come to me in my sleep, in the shower, while taking a walk, or while engaged in some other activity.

#5: Lateral thinker

While it’s important to focus on a specific problem, you should also be able to see beyond the task at hand and question the assumptions that led to the problem; this can help you predict problems and find opportunities that your client hasn’t considered.

#6: Personable

You’ll be involved in more than one company’s culture, and in each case, you’ll be seen as an outsider at the beginning. You need to be able to win the confidence of strangers who may beinitially threatened by your presence. A big dose of humor works wonders, especially when you direct it at yourself.

#7: Flexible

You will have to accommodate the priorities of multiple clients, as well as be flexible about managing your time and money. For instance, you might get an emergency phone call in the middle of the night that you can’t put off until morning; your monthly income will wax and wane as projects come and go; and sometimes you might have trouble collecting your money on time.

#8: Assertive

Although you try to be flexible on most things, you must stand your ground on the things that matter — like getting paid and maintaining your integrity. You have to be willing to lose your client in order to defend your position in both of those cases.

#9: Honest

In the long run, it is always best to speak the truth. Your integrity is your most valuable asset; once you lose it, it’s hard to get back.

#10: Realistic

This one seems to conflict with the others, but it actually tempers the other nine traits. You have to realize that you can’t work 24/7. You must give yourself a life outside consulting, so you don’t burn out. You can’t start thinking about all your outside activities in terms of how much potential billable time they’re costing you. And you have to be willing to admit when you make a mistake or need someone’s help. You’re not Superman… you’re a consultant.
