The forelegs are reduced in the Nymphalidae Diagram of an insect leg. The thorax, which develops from segments 2, 3, and 4 of the larva, consists of three invisibly divided segments, namely prothorax, metathorax, and mesothorax. [11] The organs of insect locomotion – the legs and wings – are borne on the thorax.
The first instar follows the hatching of the egg into large white larvae. The larvae are light yellow with distinctive brown heads and have soft bodies. The larvae appear to be very hairy. Following a moulting, the larvae enter the second instar. They have tubercles covered with black hair. In the third instar, large white larvae display more ...
Mature adults differ from most other blue damselflies in having expanded white edges to the tibiae, paired black markings down most of the abdomen, broad pale brown double antehumeral stripes, wider head and a pale brown pterostigmata. [2] The male has a blue abdomen that is often pale and usually has a greenish thorax. The female is a very ...
He collected caddisfly larvae from the wild and put them in climate-controlled tanks. He removes the larvae from their original cases and adds precious and semi-precious items such as grains of gold into the tank. The larvae then build new cases out of precious items, creating a unique form of artwork. The resulting works are sold across the world.
The common whitetail or long-tailed skimmer (Plathemis lydia) is a common dragonfly across much of North America, with a striking and unusual appearance.The male's chunky white body (about 5 cm or 2 inches long), combined with the brownish-black bands on its otherwise translucent wings, give it a checkered look.
Diagram of a typical insect leg. The typical and usual segments of the insect leg are divided into the coxa, one trochanter, the femur, the tibia, the tarsus, and the pretarsus. The coxa in its more symmetrical form, has the shape of a short cylinder or truncate cone, though commonly it is ovate and may be almost spherical.
Pieris rapae is a small- to medium-sized butterfly species of the whites-and-yellows family Pieridae.It is known in Europe as the small white, in North America as the cabbage white or cabbage butterfly, [note 1] on several continents as the small cabbage white, and in New Zealand as the white butterfly.

The white egg at first is elliptical (1.5 mm by 2.1 mm) but becomes more spherical as the larva inside develops. These hatch into white grubs about 18 days after laying. The newly hatched larvae are 8 mm long and grow to a length around 40 mm. Whitish with a brownish-black head, the grubs have conspicuous brown spiracles along the sides of ...
