Summary

Megaloblatta is a genus of Neotropical cockroaches in the family Ectobiidae. Species in this genus are 4 to 9.7 cm (1.6–3.8 in) long and can have a wingspan of up to 20 cm (8 in); the world's largest cockroach by length and wingspan is M. longipennis.[1][2][3]

Scientific classification Edit this classification
Domain: Eukaryota
Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Blattodea
Family: Ectobiidae
Subfamily: Nyctiborinae
Genus: MegaloblattaDohrn, 1887 Species Megaloblatta blaberoides
  • Megaloblatta insignis
  • Megaloblatta longipennis (Walker, 1868)
  • Megaloblatta regina

    • Megaloblatta, like many other insects, use stridulation in order to steer their predators away.[4] The stridulating insects are less likely to be preyed upon in comparison to individuals of the species with an inability to stridulate.[5]

    Range edit

     
    Megaloblatta blaberoides in Costa Rica; the three other species are all restricted to South America

    The four Megaloblatta species have separate distributions: M. blaberoides ranges from southern Mexico, through Central America to Colombia and Ecuador; M. insignis is restricted to French Guiana and Suriname; M. longipennis is restricted to Colombia, Ecuador and Peru (although sometimes reported from Panama, this is based on misidentifications of M. blaberoides); and M. regina is from Amazonian Ecuador and Brazil.[1][6][7][8]
