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 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.
These two articulations are perhaps the primary dorsal and ventral articular points of the subcoxo-coxal hinge. In addition, the insect coxa has often an anterior articulation with the anterior, ventral end of the trochantin, but the trochantinal articulation does not coexist with a sternal articulation.
Coloration of the male includes a dull yellow head, including its ocelli (simple eye spots), with a vertical "prout's brown" stripe from between the ocelli down to the middle of the clypeus at the bottom of the face [2] [3] The disc of the pronotum (the plate behind the head) is a reddish-brown, its sides are a translucent yellow, and the back ...
The desert cockroach can gain weight by absorption of water vapor from unsaturated atmospheres above 82.5% relative humidity.Blocking the anus or the dorsal surface with wax does not prevent water vapor uptake, but interference with movements of the mouthparts or blocking the mouth with wax prevents such uptake.
Cockroaches are experts at surviving indoors, hiding in kitchen pipes or musty drawers. A new study uses genetics to chart cockroaches' spread across the globe, from humble beginnings in southeast ...
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 ...
