description Epitheca spinigera Overview
Epitheca spinigera, commonly known as the Tiger Spiketail, is a species of dragonfly belonging to the family Corduliidae, first scientifically described in 1871. It is native to the northern and eastern regions of North America, typically inhabiting small, clear, forested streams and seepages where females lay eggs.

help Epitheca spinigera FAQ
What does the name Epitheca spinigera mean?
The name refers to a prominent physical spine found beneath the male's abdomen, which is a key identifying feature of this dragonfly species. It was first officially described by scientists in 1871. This distinct anatomical characteristic helps distinguish males from females and other similar baskettail species.
Where can I find Epitheca spinigera in the wild?
Epitheca spinigera is native to northern North America, often spotted near ponds, marshes, and slow-moving streams. They are commonly observed across Canada and the northern United States. Look for them flying low over the water during their active spring and early summer flight season.
How do you identify a male vs female Epitheca spinigera?
To identify a male Epitheca spinigera, look for the distinct, large spine on the underside of the second abdominal segment. Females lack this prominent spine but may have a more robust abdomen, especially when carrying eggs. Both sexes feature the typical baskettail coloring, which is usually a brown or black body with yellowish markings.
What family does the Epitheca spinigera dragonfly belong to?
Epitheca spinigera belongs to the Corduliidae family, which encompasses the emerald dragonflies and baskettails. They are characterized by their robust bodies and hunting habits, often patrolling over water. This family is distinct from the common skimmers or darners found in similar habitats.
