When the cockroach has recovered from the first sting, it makes no attempt to flee. The wasp clips the antenna with its mandibles and drinks some of the haemolymph before walking backwards and dragging the roach by its clipped antenna to steer it to a burrow, where an egg will be laid on it. The wasp larva feeds on the subdued, living cockroach.
The Peltoperlidae, also known as roach-like stoneflies or roachflies, are a family of stoneflies. The family Peltoperlidae comprises 11 genera and 46 known species. [2] Species are semivoltine, meaning their lifecycles last one to two years. Adults of the family usually emerge in late spring or early summer, April through June.
The American cockroach (Periplaneta americana) is the largest species of common cockroach, and often considered a pest. In certain regions of the U.S. it is colloquially known as the waterbug, [1] though it is not a true waterbug since it is not aquatic. It is also known as the ship cockroach, kakerlac, and Bombay canary. [2]
The earliest cockroach-like fossils ("blattopterans" or "roachoids") are from the Carboniferous period 320 million years ago. [11] [12] [13] Fossil roachoids are considered the common ancestor of both mantises and modern cockroaches, and are distinguished from the latter by the presence of a long external ovipositor.
The German cockroach (Blattella germanica), colloquially known as the croton bug, is a species of small cockroach, typically about 1.1 to 1.6 cm (0.43 to 0.63 in) [1] [2] long. In color it varies from tan to almost black, and it has two dark, roughly parallel, streaks on the pronotum running anteroposteriorly from behind the head to the base of ...
Plecoptera is an order of insects, commonly known as stoneflies.Some 3,500 species are described worldwide, [1] with new species still being discovered. Stoneflies are found worldwide, except Antarctica. [2]
The number of segments in an antenna varies amongst insects, with higher flies having 3-6 segments, [21] while adult cockroaches can have over 140. [22] The general shape of the antennae is also quite variable, but the first segment (the one attached to the head) is always called the scape, and the second segment is called the pedicel.
Species in this genus are 4 to 9.7 cm (1.6–3.8 in) long and can have a wingspan of up to 20 cm (8 in); the world's largest cockroach by length and wingspan is M. longipennis. [1] [2] [3] Megaloblatta, like many other insects, use stridulation in order to steer their predators away. [4]
