- Insects (from Latin insectum) are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within.

The Central Area, commonly called the Central District or The CD, is a mostly residential district in Seattle located east of downtown and First Hill (12th Avenue and Rainier Avenue); west of Madrona, Leschi and Mt. Baker; south of Capitol Hill, and north of Rainier Valley. Historically, the Central District has been one of Seattle’s most racially and ethnically diverse neighborhoods, and was once the center of Seattle’s black community and a major hub of African-American businesses.
