Aquatic Insects Such:
Respiration is by gills in aquatic insects such animals that have never left the aquatic insects such environment. The blood is usually oxygenated by traveling through vessels spread out in feathery gills that trap the oxygen dissolved in the water. In terrestrial ani¬mal forms that have reverted to an aquatic insects such habi¬tat, respiration is by lungs and is accomplished at the surface of the water. (In some isolated cases of insects and spiders, the air is entangled in their hairs and conveyed into their submerged homes.) Transitional methods of respiration can be observed in larval insects, crustaceans, and fishes on land with a minimum of water about their gills, and also in the air- and water-breath¬ing fishes.In the wild, cooters and sliders feed on aquatic insects such insects, aquatic insects such plants, small fish, aquatic insects such snails, and tadpoles; adults feed more heavily on plant life than do turtle young. Offer aquatic insects such plants, fresh, green vegetable tops, fruit in season, especially melon rinds, bits of raw meat. Try hamburger and meal worms. Keep piece of fresh, green lettuce on water at all times.

Development of flying insects —for Ability. The first animal to acquire the capability of flight was the insect. Although the exact time in geological history when the first winged insect appeared is un¬certain, it is known from rock-embedded fossils that a variety of flying insects —for insect forms were already in existence well over 300 million years ago. Some flying insects —for insects—for example, the dragonfly and the cockroach—have essentially the same form today as that of their earliest fossils. Well over 650,000 species of flying insects —for insects have al¬ready been classified, and no doubt many thou¬sands more exist in the various unexplored regions of the earth. The first vertebrate animal to evolve wings was the reptile. The reptilian aeronauts—the pterosaurs—first appeared about 150 million years ago. The largest of the pterosaurs—Pteranodon —sometimes attained a wingspread of 25 feet ( 7.7 meters). Although the membranelike wings of Pteranodon were articulated for flapping, it is probable that they were more commonly used for soaring flight. Pterosaurs existed for about 60 million years before becoming extinct.Feed on wide variety of insects and worms; largest frogs also eat small fish, small birds, and the smaller amphibians. Note— Frogs maintained in Outdoor pools often leave pool, will even negoti¬ate house steps, to get at screen door so as to capture night-flying insects —for insects drawn to door by Light left on in room. This is fascinating to watch. Eat all kinds of insects—both adults and larvae—worms, and smooth-skinned caterpillars.
On The Other Hand See Destructive Insects:
Insects are also important as a major source f food for many birds, fish, amphibians, reptiles, nd mammals. In some parts of the world they re eaten by man. Various types of water beetles, nts, termites, grasshoppers, and large beetle irvae are used as food in Asia, South America, nd other regions. Another important use of insects is in the liological control of other, destructive insects. An xample of this type of biological control was the uccessful control of the destructive coconut moth n Fiji by the introduction of tachinid flies, nat-ral parasites of the coconut moth. In the United tales, vedalia beetles were used to control the ottony cushion scale, a pest of citrus trees.Plants as well as animals are subject to insect attacks, and every year millions of dollars worth of agricultural crops are destroyed by insects. Every crop is vulnerable to destructive insects, during each stage of its growth. The larvae of beetles, flies, and some moths attack the roots of young seedlings, and cutworms and some other types of insect larvae eat the young shoots at ground level. Stem sawflies burrow into the stems Df cereal plants, causing them to break off. Suck¬ing insects remove a great deal of sap, thus reducing the vitality of plants.
