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 →

Rare
Under 5% of wildlife watchers report an Orange Bluet sighting in Houston on a given day, based on 28 verified sightings from GBIF citizen-science data. It is the 418th most-seen of the 1057 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Orange Bluet in Houston on a given day, so our monthly data shows no clear season.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Orange Bluet sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Among the best
Of the 14 cities where we can rate Orange Bluet sightings, Houston ranks 9th at under 5%, level with the leaders once rounded. The best odds are in New York City (United States, under 5%), Washington (United States, under 5%) and Toronto (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Orange Bluet is recorded against all the insects logged in Houston (28 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
