Writing an article about insects requires physical characteristics, calls and living habits (such as eating, living and moving). ), ask to write clearly.

Dung beetles, commonly known as dung beetles, belong to COLEOPTERA. Black or dark brown body, large and medium-sized insects. Dung beetles can locate themselves by moonlight polarization and help them find food. It has certain phototaxis. There are more than 20,000 species of dung beetles in the world, which are distributed in any continent except Antarctica. The most famous dung beetles lived in Egypt and was1-2.5cm long. The largest dung beetles in the world is the giant dung beetles with a length of10cm. Dung beetles are mostly dung-eating animals, which feed on animal dung and are known as "natural scavengers".

Living habits

Dung beetle is an insect with a spoon-shaped head, which can turn feces into balls. They lay eggs on this spherical feces and bury them, so that the larvae can have ready-made food when they hatch. There are more than 20,000 species of dung beetles in the world, which are distributed in any continent except Antarctica. The most famous dung beetles lived in Egypt and was1-2.5cm long. The largest dung beetles in the world is the giant dung beetles with a length of10cm. Dung beetles are mostly dung-eating animals, which feed on animal dung and are known as "natural scavengers". It often makes the feces into balls, rolls them to a reliable place to hide, and then eats them slowly. Dung beetles can roll a dung ball much bigger than himself. Female dung beetles in the breeding season will turn dung balls into pears and lay eggs in them. Hatched larvae feed on ready-made dung balls, and they don't break out of their shells until they grow into adult dung beetles. Plant-eating dung beetles feed on sweet tree juice. After mating, female dung beetles lay eggs in humus soil. After about 10 days, the larvae break out of their shells and feed on humus or animal feces. Larvae keep growing, pupate in July of the following year, and become adults in about 20 days. Dung beetles belong to Insecta, COLEOPTERA, with black or dark brown body, hard exoskeleton, developed compound eyes, chewing mouthparts, leaflike tentacles and gills, three pairs of feet, suitable for digging, two pairs of wings, keratinization of front wings, and complete metamorphosis. Dung beetles can locate themselves by moonlight polarization and help them find food. It has certain phototaxis.

morphological character

Dung beetles was black and slightly shiny. The male is 3.3 ~ 3.5m long, while the female is slightly smaller. The front of the male worm's head is fan-shaped, with fish-scale wrinkles on the surface and a large, slightly square-shaped angular protrusion in the center; There are compound eyes on both sides of the back, and there is a bright and wrinkle-free narrow band between them. The chest backboard is densely covered with symmetrical small round protrusions, and there is a transverse ridge in the middle. The middle of the ridge is slightly bent forward into an obtuse angle shape, and there are 1 dentate angular protrusions on both sides. There are shallow depressions in front of and behind the dentate protrusions, and the bottom is smooth without small round protrusions. There is a deep depression outside the shallow depression, and the small round protrusions at the bottom are very vague or missing. The small shield is invisible; The front wing is a sheath wing, which is quite upturned and covered with dense wrinkles, and there are 7 recognizable longitudinal lines on each side; Posterior wing membranous, yellow or yellowish brown. There are many brownish red or brownish yellow cilia in the mouth and chest, and there are rows of brownish red burrs on both sides of the middle and rear tarsal joints. The female insect is very similar to the male insect in appearance, except that the center of the head is not angular, but the back is flat, the front is oblate and the top has a horizontal ridge; The transverse ridge of the thoracic backboard is approximately straight, with no teeth at both ends, and only the lateral deep depression is obvious.
