Etymology

The genus name Somatochlora means "green bodied", referring to the metallic green coloration of some of its members. The specific epithet minor refers to its small size.[8]

The common name refers to the eye-like spots on the sides of the adult's thorax and the species classification as an emerald.[8]

Behavior

The ocellated emerald often perches on vegetation near small streams between patrols flying close to the water surface.[7]

It oviposits using either repeated taps of moving water or alternating taps of the water surface near the shore and mossy bank above.[7]

Distribution

The ocellated emerald can be found across much of Canada and parts of the northern United States.[7]

Habitat

The ocellated emerald inhabits small to medium, slow to moderately fast streams with pools, in forested or open surroundings.[7]
