Features and Behaviors
FEATURES
The turquoise bluet is one of fifteen bluet species found in Illinois. It is about 1.5 inches long, has a prominent blue tip on the abdomen, and post-occular spots (spots on the head behind the eyes) that form a dumbbell shape. Males have blue eyes while females have tan to brown eyes. Many in this genus are difficult to differentiate. They all look very similar and sometimes change color with age, so examination of reproductive parts is usually necessary for species level identification.
BEHAVIORS
The turquoise bluet can be found in the southern quarter of the state, along small woodland streams and swampy areas. They fly from May to July. There is not much information available on their life histories, including life span, mating, and feeding.
