List of cockroaches of Sri Lanka explained

Sri Lanka is a tropical island situated close to the southern tip of India. The invertebrate fauna is as large as it is common to other regions of the world. There are about 2 million species of arthropods found in the world, and counting.

The following list is about Cockroaches recorded in Sri Lanka.

Cockroach

Phylum: Arthropoda
Class: Insecta
Order: Blattodea

Cockroaches are insects of the order Blattodea, which also includes termites. About 30 cockroach species out of 4,600 are associated with human habitats. About four species are well known as pests. Cockroaches are somewhat generalized insects without special adaptations like the sucking mouthparts of Hemiptera; they have chewing mouthparts and are likely among the most primitive of living neopteran insects. They are common and hardy insects, and can tolerate a wide range of environments from Arctic cold to tropical heat. Tropical cockroaches are often much bigger than temperate species, and, contrary to popular opinion, extinct cockroach relatives and 'roachoids' such as the Carboniferous Archimylacris and the Permian Apthoroblattina were not as large as the biggest modern species.

Cockroaches are members of the order Blattodea, which includes the termites, a group of insects once thought to be separate from cockroaches. Currently, there are 4,600 species described and over 460 genera worldwide.[1] [2]
