The orange bluet (Enallagma signatum) is a species of damselfly in the family Coenagrionidae. This species of bluet stands out from many other bluets because of its orange color. On male orange bluets, the thorax is orange with a thick, black stipe along the back and black shoulder stripes. His abdomen is mostly black with some orange rings, orange below, and orange near the tip. His large eyes are orange on a black head; small orange postocular spots are connected across the back of the head by an orange bar. On female orange bluets, the thorax is similar looking to the male thorax only the color is dull yellow instead of orange. Her abdomen is mostly black above and dull yellow below. Her large eyes are yellow-brown with small yellow postocular spots connected by a thin, yellow bar. The female can also be one of three forms. The first remains blue throughout life, one becomes green and the third becomes orange.
This bluet is often found near streams, ponds, pools with still waters, slow moving streams, and rivers. Mexico: Tamaulipas United States: (Colorado • Georgia • Massachusetts • New Jersey • Ohio • Vermont) Canada: (New Brunswick... Wikipedia →
