Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The thin-waisted social wasps (genus Microstigmus), which typically resides in neotropic regions from Central to South America, are a small genus of wasps that build nests and live in colonies ranging in size from 1 to 18 members.cite_ref-Matthews_0-0 Microstigmus is widely considered to be the only true eusocial species within the Crabronidae family.cite_ref-1 Like all Hymenoptera, Microstigmus has an interesting sex determination pattern. Females are 2n (diploid), spawning from eggs that have been fertilized, while males are 1n (haploid) and spawn from unfertilized eggs. Female wasps contain the eggs within their egg sac and have the option of fertilizing them or not, thus having complete control on the gender of the offspring.cite_ref-Lucas_2-0 This wasp genus, part of the suborder Apocrita, is distinguished physically by the narrow waist (petiole) between the end segment of the thorax (mesosoma) and the beginning of the abdomen (metasoma).
