Cordulegastridae nymphs will almost entirely conceal themselves in sand or silt, exposing only their eyes to see, antennae for sensing prey, and the tip of their abdomen to breathe dissolved oxygen. [11] Nymphs will consume any prey they can capture, going as far as eating smaller larvae of the same species. [12]
Megarhyssa male adults reach body lengths going from 2.3 to 3.8 cm (0.9 to 1.6 inches), while female adults can measure from 3.5 to 7.5 cm (1.5 to 3 inches). [3] Both sexes can be distinguished because females have an extremely slender, and long organ to lay eggs called the ovipositor.
Megarhyssa nortoni is a predatory insect. Its larvae are parasitoids of horntail wasp larvae in coniferous trees. The adult female hunts horntail larvae for egg placement. It smells wood-eating fungus, utilized by the horntail larvae to predigest wood pulp, and uses its antennae to detect vibrations made by the horntail larvae.
The body of an adult Scutigera coleoptrata is typically 25 to 35 mm (1.0 to 1.4 in) in length, although larger specimens are sometimes encountered. [6] Up to 15 pairs of long legs are attached to the rigid body. Together with the antennae they give the centipede an appearance of being 75 to 100 mm (3 to 4 in) in length. [6]
The facial plate (below and between antennae) is about twice as wide as it is long, typical of the genus, though the eyes are not as protruding as the Carolina Mantid's. Females are most often fairly plain green (often with a yellowish abdomen), but sometimes gray, or light brown, with dark spot in middle of the tegmina , which do not ...
Both the confused flour beetle and red flour beetle are small, about 3–6 mm (1/ 8 + 1 ⁄ 4-inch) in length, and reddish-brown in color. The primary distinguishing physical difference is the shape of their antennae: the confused flour beetle's antennae increase gradually in size and have four clubs, while the red flour beetle's antennae have ...
Megarhyssa macrurus, also known as the long-tailed giant ichneumonid wasp [1] or long-tailed giant ichneumon wasp, [2] is a species of large ichneumon wasp. [3] It is a parasitoid, notable for its extremely long ovipositor which it uses to deposit an egg into a tunnel in dead wood bored by its host, the larva of a similarly large species of horntail.
Adult Stage [3] 3/4 to 1 and 1/4 inches long; dark brown to black long abdomen; red or orange thorax and legs; small down pointed head with short 10-segmented antennae; wings have dark spot on R1 (leading edge, 2/3 of the wing from body) feed mostly on liquids like water or nectar; Bibio femoratus gets its name from its bright red femurs.
