大自然中,芸芸众生各有特色,各有各的活法。蝼蛄是直翅目昆虫中独具特色的一类,它不像飞蝗那样在光天化日下猖狂,也不像蟋蟀唧唧哀鸣,而是默默然潜藏于地下,啮食作物的苗根,使成片幼苗枯死。蝼蛄为适应地下生活,成虫体形呈纺锤形,锥形的头部背面丛生鬃毛,两对翅短小而不发达。三对足却别有特色:因为前足要挖土掘进,后足需有力蹬推,所以前足长得犹如扁平的掘土铲,端部有坚锐的扁齿,后足股节发达粗壮。腹部末端有细长尾须一对。幼虫初孵出时全身乳白色,唯有复眼为淡红色,头部黑色,随着时间的推移,幼虫体色逐渐变为黑褐色。蝼蛄成虫利用前足在土壤中开掘隧道。开掘的隧道通常有50厘米深,最深者可达150厘米。这种隧道
In nature, all living beings have their own characteristics, each with its own living law. Scabies is a unique category of Orthoptera insects, it is not like Wild Migratory locust in rampant daylight, nor as crickets whirring, but silently hidden in the ground, feeding the seedling root crops, into a film Seedlings dead.蝼 蛄 In order to adapt to underground life, the adult body was spindle-shaped, tapered head of the tufted bristles, two pairs of wings short and undeveloped. Three pairs of feet but do not have the same characteristics: because the front foot to dig digging, after foot force push, so the forefoot looks like a flat dig soil shovel, the tip has a sharp flat teeth, developed sturdy hind legs section. Abdomen tail ends of a pair of slender. Early larvae hatched body milky white, only compound eyes as pink, black head, as time goes by, the larva body color gradually turns dark brown. Wren adults use the forefoot to dig the tunnel in the soil. The digging tunnel is usually 50 centimeters deep, the deepest up to 150 centimeters. This kind of tunnel
