The cockroach is divided into three sections; the body is flattened and broadly oval, with a shield-like pronotum covering its head. A pronotum is a plate-like structure that covers all or part of the dorsal surface of the thorax of certain insects.
The head capsule bears most of the sensory organs, including the antennae, ocelli, and compound eyes, along with the mouthparts. In the adult insect, the head capsule appears unsegmented, though embryological studies show it to consist of six segments that bear the paired head appendages, including the mouthparts, each pair on a specific ...
Parcoblatta zebra, the banded wood cockroach, is a species of Parcoblatta native to the United States. [2] It has dark transverse bands across the back of its abdomen. [ 3 ]
The head has a pair of long, slender antennae, two large compound eyes and two protuberant ocelli. The labrum is broad, and the frons and the hinder part of the clypeus are fused and form a bulge in a manner unusual for cockroaches. The pronotum is large and covers the head
The male Parcoblatta fulvescens is relatively slender, has long tegmina (outer forewings), and is slightly longer than the female. [3] It is a mostly uniform pale brownish-yellow, with sometimes darker pronotum (the plate behind the head) and legs, and usually dark brown cerci (the pair of appendages on its rear-most segment). [3]
The male dorsal coloration of the species is a glossy light brown or reddish brown, while the female is a darker brown. [5] The male's tegmina (outer forewings) extend well beyond the abdomen, and are wider than its pronotum. [4] The female's short tegmina end around the second dorsal segment, and are colored slightly lighter than the rest of ...
The male is the most slender of the larger pale species in the genus. Its pronotum is relatively long for the genus. [4] It has fully developed tegmina and wings. [4] It has a specialization on the median and first dorsal abdominal segments: on the median segment are two subtriangular, rounded elevations with very heavy tuft of hairs, and a few scattered hairs on the rest of the segment; on ...
The cockroach is flattened dorsolaterally and is roughly oval with a shield-like plate, the pronotum, covering its thorax and posterior region of the head. The antennae are many-segmented, long and slender, and the mouthparts are adapted for chewing. The forewings are normally leathery and the hind wings membranous.
