The fossils assigned to the "roachoids" are of general cockroach-like build, with a large disc-like pronotum covering most of the head, long antennae, legs built for running, flattened body and heavily veined wings with the distinct arched CuP-vein so typical of modern cockroach wings. [9] Like modern cockroaches, the roachids were probably ...
Dictyoptera (from Greek δίκτυον diktyon "net" and πτερόν pteron "wing") is an insect superorder that includes two extant orders of polyneopterous insects: the order Blattodea (termites and cockroaches together) [1] and the order Mantodea (mantises). All modern Dictyoptera have short ovipositors and typically lay oothecae.
The earliest cockroach-like fossils ("blattopterans" or "roachoids") are from the Carboniferous period 320 million years ago. [12] [13] [14] 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 ...

The oriental cockroach (Blatta orientalis), also known as the waterbug (as they live in damp areas) or black cockroach (as their bodies are mostly dark), [1] is a large species of cockroach, adult males being 18–29 mm (23 ⁄ 32 – 1 + 5 ⁄ 32 in) and adult females being 20–27 mm (25 ⁄ 32 – 1 + 1 ⁄ 16 in).

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. The remaining antennal segments or flagellomeres are called the flagellum. [17]: 8–11 General insect antenna types are shown below:
