Cathemeral, a classification of organisms with sporadic and random intervals of activity during the day or night.

Immature cockroaches emerge from egg cases in 6–8 weeks and require 6–12 months to mature. After hatching, the nymphs feed and undergo a series of 13 moultings (or ecdysis). Adult cockroaches can live up to an additional year, during which females produce an average of 150 young. The American cockroach reproductive cycle can last up to 600 ...
While cockroaches do, indeed, have a much higher radiation resistance than vertebrates, with a lethal dose perhaps six to 15 times that for humans, they are not exceptionally radiation-resistant compared to other insects, such as the fruit fly. [67] The cockroach's ability to withstand radiation has been explained through the cell cycle.
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).

Here’s how to get control of these bacteria-carrying pests. Like worrisome termites, cockroaches have a job to do, breaking down organic matter in the natural world.But even one cockroach isn ...
The German cockroach reproduces faster than any other residential cockroach, [15] growing from egg to reproductive adult in roughly 50 – 60 days under ideal conditions. [16] Once fertilized, a female German cockroach develops an ootheca in her abdomen. The abdomen swells as her eggs develop, until the translucent tip of the ootheca begins to ...
The researchers also looked at death records and, after adjusting for factors like alcohol use, smoking, body mass and sleep duration, found that night people had a 9% greater risk of early death ...
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 ...
