How To Be Friends With A Fly
The poet Ogden Nash put it succinctly: "God in His wisdom / Fabricated the fly /
And and then forgot / To tell the states why."
True, information technology's blackfly season, which is possibly not the all-time time of year to convince y'all that some flies are our friends. Merely not all flies deserve the disgust we heap on the tribe, for there are species that control pests, pollinate flowers, and some that are even beautiful in their way. At that place is more to flies than the malaria-conveying mosquitoes and the tsetse of crossword puzzle fame.
The true flies brand up a various group of insects called the Diptera, so named because they take simply two (di-) wings (-ptera). That'southward a central trait for the fly-watcher, for many beneficial flies mimic the behaviors of bees and wasps, which have four wings.
The most endearing of the benign flies, the syrphid or "hover" flies, are among these bee/wasp await-alikes. They are very mutual, just because they typically wear black-and-yellow bee suits and act then much like bees, they are usually mistaken for them. Watch for syrphid flies near flowers, where they may hover motionless for long periods of time. The adults are nectar- and pollen-feeders, and afterwards bees, they are the about important insect pollinators.
Syrphid fly virtues are not limited to the adults, though. The larvae of some species are predators that specialize on aphids. If you are unlucky plenty to have a hearty population of aphids on your home fruit trees, take a shut look. You may run across a small animate being that looks sort of, but not quite, like a headless caterpillar, swinging the narrow forepart stop of its trunk from side to side in search of an aphid. Once contact is fabricated, the larva hooks onto the aphid and sucks it dry. Past the time it is mature, the larva is eating 60 aphids a twenty-four hours.
The "bee flies" are some other family of flower-pollinating flies whose members often await similar bees – but bees with long, stiletto-like proboscises. They are hairy beasts, sometimes striped, sometimes with patterned wings. I mutual and widespread species, the greater bee fly (Bombylius major), holds its ii, nighttime-bordered wings out at an angle while at rest, giving the fly the look of a miniature stealth fighter on Rogaine. Bee flies, like syrphid flies, let their larvae do the muddy work: in this example, parasitizing cutworms, protrude grubs, bee and wasp larvae, and grasshopper eggs.
With the tachinid (tak' i nid) flies, we leave behind the bee mimics. Many tachinids wait more or less similar the basic house fly, although there is some variety in color, size, and shape. What they lack in visual appeal, however, the tachinids brand upwardly for in their importance equally the natural enemies of plant pests. The larvae of the entire family of over i,300 species are parasitic on insects. Their victims are mostly caterpillars and adult and larval beetles, though some tachinid flies kill sawfly larvae, true bugs, grasshoppers, and other insects. Several species of tachinid flies have been imported as control agents for pests, with varied success.
The smoke-colored wings and orangish abdomen of i of the native tachinids, Trichopoda pennipes, may catch your heart as it hovers over squash plants in the garden. It lays its eggs on those pesky squash bugs and other true bugs. When the eggs hatch, the larva burrows into its host and consumes it from the inside out.
Some other family of fly-like flies, the blow flies, contributes to pest control too. 1 hitting example is that of Sarcophaga aldrichi, a parasite of the forest tent caterpillar. The wood tent caterpillar undergoes regular population explosions during which it strips its hardwood habitat bare of leaves. Enter our hero(ine). With so many hosts available, the fly population builds and builds. Finally, parasitism becomes so heavy that caterpillar numbers crash. During peak periods, the flies are then abundant that they become a existent nuisance. Its numbers, active flight, fondness for sugar, and addiction of landing on people have earned Sarcophaga aldrichi the name, "the friendly wing."
At that place has been much research about how to attract and keep beneficial flies in the garden. The obvious key is to provide what they need: safe places to hide and rest, an environs free of insecticides, and, for bee flies and syrphid flies, nectar and pollen. The flies, who are not as smart, strong, or long-tongued as bees, favor plants with numerous small flowers that have easily available nectar and pollen. For this reason, some of the best plants for attracting beneficial flies are sweet alyssum, buckwheat, and members of the carrot family, such as dill, Queen Anne's lace, parsley, caraway, and fennel.
Making homes for these flies, and so, is a winning proposition: more flowers, more than flies. So hold off on the Flit.
