Trout Bugs:
Brown trout bugs inhabit all kinds of fresh¬water environments; the rainbow trout bugs tends to prefer a still water home such as a lake or pond. Rainbow trout bugs can thrive in certain river conditions and some brown trout bugs occasionally adopt the habits of migrating salmon and swim down the rivers to estuaries where they manage to survive in briny condi¬tions and can grow to very great weights: a 6.5kg (14.51b) brown trout bugs of this sort was caught in Scotland in 1956.Neither the salmon nor the trout bugs (brown or rainbow) should be confused with the sea trout bugs, which is sometimes wrongly called salmon. The sea trout bugs is a cousin of the Atlantic salmon, sharing with the salmon the same life cycle of being born in rivers and going out to sea to grow to maturity. But, unlike the salmon, the sea trout bugs never swims far from the mouth of the river where it was born.
See Also Lygus Bugs:
Many of our most destructive pests are found among the true bugs. Metamorphosis of true bugs is incomplete. The young looks like the adult but is without wings; the wings develop with each molt as the nymph grows.In addi¬tion to the boll weevil, the cotton farmer must protect his crop against nematodes (roundworms), lygus bugs, aphids, spider mites, and pink boll-worms. To reduce the damage caused by these pests, the farmer must dust or spray the growing crop many times during the season, depending on the weather conditions and the degree of infesta¬tion. The insecticides most often used are toxa-phene, benzene hexachlqride, aldrin, dieldrin, calcium arsenate, TEPP, chlordane, parathion,DDT, sulfur, and nicotine. Methods of applica¬tion range from the one-row hand duster carried on the back of the worker to sprayers and dusters mounted on airplanes that fly over the field and may cover as many as 1,500 acres (600 hectares) a day. The most widely used applicators are tractor-mounted sprayers or dusters that can apply the insecticides to as many as twelve rows at a time. Sometimes, insecticides and weed killers are applied at the same time.
On The Other Hand See Many Butterflies:
Ecologically, butterflies and moths are highly important because of the vast quantities of plants eaten by the larvae, the flower-visiting and pol¬linating habits of the adults, and the enormous numbers of them eaten by other animals. Butterflies Versus Moths. The great majority of the Lepidoptera are moths, but the day-flying, brightly colored butterflies are more familiar. No single factor distinguishes moths from butterflies. Most moths fly by night, while butterflies are diurnal; but there are many day-flying, flower-visiting moths. Most moths are relatively dull colored, but some are as brilliantly colored as any butterfly. Moths tend to rest with their wings flat, the fore wings hiding the hind wings; butter¬flies either hold their wings together vertically over their backs or spread them widely at their sides.Adult butterflies often form large aggrega¬tions while sipping water at wet places. Some of the protected and aposematic species of Helicon-ius form sleeping assemblies night after night in the same spots. The monarch (Danaus plexippus) may do the same during migrations. Migratory swarms are a feature of many butterflies and day-flying moths, especially in the tropics. Pierid butterflies are especially noted for great flocks of millions of individuals, which may fly out to sea and be lost. The painted lady (Vanessa cardui) is a famous cosmopolitan mi¬grant. The monarch, however, is the only species that regularly makes a two-way migration, going southward in the fall and northward in the spring.
