Systematic Position

The word “cockroach” is derived from the Spanish word cucaracha, which was converted into “cock” and “roach” by 1620s English folk etymology. The scientific name comes from the Latin word blatta, which meant “light-sleeping bug” in Classical Latin and related to both mantis and cockroaches.

The term system comes from the Latin Greek systema, and was applied to the taxonomy developed by the early naturalists, especially Linnaeus. Systematics is generally defined as the study of biological diversity and relationships between organisms. Taxonomy often makes a distinction between the highest taxonomy and the taxonomy of a species. Systems plays a central role in biology, providing the means to characterize the organisms we study. It also allows predictive and testable hypotheses by creating classifications that reflect evolutionary relationships.

Systematic Position

• Cockroaches are scientifically known as Periplaneta americana.
• They belong to the kingdom group of invertebrates. 
• They have articulating appendages that place them in the phylum Arthropoda, the largest phylum in the animal kingdom. 
• Having six pairs of legs and a pair of wings allows taxonomists to assign them to the Insecta class.
• These creatures may be found all throughout the world and enjoy wet, dark, and moist environments.

Biological Classification

Most cockroach species  are thumbnail size, but some species are larger. The  heaviest cockroach in the world is the Australian giant burrowing cockroach Macropanesthia rhinoceros, which can reach 8 centimeters (3 inches) in length and weigh up to 35 grams (1.2 ounces). The Central American giant cockroach, Blaberus giganteus, of similar size. The longest cockroach species is Megaloblatta longipennis, which can be up to 97 mm (3 + 7/8 inches) long and 45 mm (1 + 3/4 inches) wide.

The cockroach family Anaplectidae, Lampro Blattidae, and Tryonicidae are not listed, but are classified in the superfamily Brattoidea. The cockroach family Corydiidae and Ectobiidae were formerly known as Corydiidae and Ectobiidae.

 Dictyoptera: This is a vegetation containing two existing orders of Polyptera: Order Blattodea and Order Mantodea (mantis). All modern Dictyopteras have short oviducts, but the oldest Dictyoptera fossils have long oviducts, like Orthoptera.

Mantodea: Mantis is an insect order (Mantodea) with more than 2400 species in 33 families, 460 genera. The largest family is the Mantidae (“Mantis”). Mantis are found in temperate and tropical settings all over the world. They have a triangular head with bulging eyes supported by a flexible neck.

Blattodea: An insect order that includes cockroaches and termites. Although termites were considered a separate order of Isoptera, genetic and molecular evidence indicates that termites are descendants of the cockroach lineage, making them taxonomically cockroaches. Blattodea and mantis (Order Mantodea) are now considered part of the vegetation Dictyoptera. Blattodea contains about 4400 species of cockroach in nearly 500 genera and about 3000 species of termites in about 300 genera.

Blattoidea: It is a superfamily of cockroaches and termites (Blattodea). Blattoidea contains about 17 families and more than 4100 described species. Twelve termites are sometimes considered members of the suborder Isoptera, but a recent phylogenetic analysis place them in the cockroach superfamily Blattoidea. Within Blattoidea, termites are classified in the family Termitoidae epi.

Corydioidea: This is a superfamily of Blattodea, cockroach and termite insects. It includes two extant families, Corydiidae and Nocticolidae, which contain about 50 genera and 250 species, and the extinct lineage Liberiblattinidae. Members of this superfamily are found worldwide, mainly in hot and dry habitats.

Ectobiidae: (formerly Blatteellidae) is a family of the order Blattodea (cockroach). This family includes, among other things, many small domestic pests’ cockroaches. They are sometimes called tree cockroaches.

Blattoidea: It is a superfamily of cockroaches and termites (Blattodea). Blattoidea contains about 17 families and more than 4100 described species. Twelve termite families are sometimes considered members of the suborder Isoptera, but recent phylogenetic analyzes have included them in the cockroach superfamily Blattoidea. Within Blattoidea, termites are classified in the epifamily of Termitoidae.

Blaberidae: The giant cockroach, or blaberid, is the second largest cockroach family in terms of species number.

Termites: Termites were once placed in a separate order from cockroaches, but recent phylogenetic studies have shown that when nesting deep within a group, they descend from cockroaches and pass from a sister group to tree cockroaches of the genus Cryptocercus.

Conclusion

Cockroaches are one of the most common pests in many homes and other areas. At night, they find food in the kitchen, food pantry, and trash can. Tanks, drains and drains. They are pests because of their dirty habits and bad smell. Thus, systematic position is a framework used for the evolution of life. Systems play a central role in biology, providing the means to characterize the organisms we study. It also allows predictive and testable hypotheses by creating classifications that reflect evolutionary relationships.
