What are the small bean-like capsules produced by adult female cockroaches called?

The small bean-like capsules produced by adult female cockroaches are called oothecae. This term specifically refers to the egg cases that house the developing eggs of cockroaches. Each ootheca can contain multiple eggs, and the female typically carries the ootheca until the eggs are close to hatching. This reproductive strategy helps protect the eggs from environmental dangers and increases the likelihood of their survival.

In contrast, egg sacks and larvae pods are not scientifically accurate terms used in entomology to describe cockroach reproduction. The term "chrysalis" is also unrelated, as it refers to the pupal stage of insects like butterflies and moths, which is distinctly different from the life cycle of cockroaches. Understanding these distinctions helps clarify the unique aspects of cockroach biology and their reproductive mechanisms.
