The genus leucorrhinia, or the whitefaces, all have whitefaces as their name would suggest. Most are a combination of black and yellow or black and red. Some change color due to pruinose, a powdering substance that some dragonflies produce as they age. All whitefaces have black legs.
The dot-tailed whiteface is the most common whiteface found in Minnesota. It can be found in every county in the state, unlike the other whitefaces that are limited geographically. The mature male is mostly black with a single square shaped black spot on the top of abdominal segment seven, see the first picture for an example. Females and juvenile males have yellow top spots on segments one through seven, see the picture above. Dot-tailed white faces are usually found around ponds, marshy areas, as well as quiet lakes and streams.
Dot-tailed whiteface often perch on vegetation in the water, such as lily pads and algae beds. Males are often seen defending their territory from such perches. Even copulation typically takes place on floating vegetation, as pictured above. After they finish the female will lay the eggs in the water next to some floating vegetation. The male will hover guard while she lays the eggs making sure no other male can get to the female until after she has finished bearing his future offspring.
