Variable Dancer (mating pair, “in heart”)

November 23, 2016

A mating pair of Variable Dancer damselflies (Argia fumipennis violacea) was spotted at Mulligan Pond, Jackson Miles Abbott Wetland Refuge (JMAWR). This pair is “in heart“: the male is on the upper-left; the female on the lower-right.

The taxonomic classification of Variable Dancer is as follows: Order Odonata (Dragonflies and Damselflies); Suborder Zygoptera (Damselflies); Family Coenagrionidae (Narrow-winged Damselflies); Genus Argia (Dancers); Subspecies Argia fumipennis violacea (Violet Dancer).

Variable Dancer is a habitat generalist that can be found almost anywhere there is water. Mature males are easy to recognize due to their unique coloration — there are no other species of violet damselflies found in the eastern one-third of the United States. Female Variable Dancers, like many female odonates, are more challenging to identify than males.

It’s helpful to get shots of mating pairs of damselflies, especially “in tandem,” since males and females of the same species can look quite different. The excellent high-resolution digital scans by Gayle and Jeanelle Strickland, listed under “Related Resources” (below), provide clear views of male and female Variable Dancer damselflies.

Family Coenagrionidae (Narrow-winged Damselflies) is comprised of 14 genera. Three genera are common in Northern Virginia: Argia (Dancers); Enallagma (American Bluets); and Ischnura (Forktails).

Several species of Argia are relatively common in Northern Virginia parks: Blue-tipped Dancer and Variable Dancer are featured in this post; Blue-fronted Dancer was featured in a recent blog post.

Blue-tipped Dancer

The first photo shows a Blue-tipped Dancer damselfly (Argia tibialis) perching on a sandy beach in the stream bed of Dogue Creek, Wickford Park. This individual is a male, as indicated by its coloration.

Variable Dancer

The next photo shows a Variable Dancer damselfly (Argia fumipennis) perching on vegetation along Dogue Creek, near Huntley Meadows Park. This individual is a male, as indicated by its coloration.

The last photo shows a mating pair of Variable Dancer damselflies (Argia fumipennis) spotted at Huntley Meadows Park (HMP). The pair is in tandem (a form of guarding behavior): the male (upper-left) guides the female (lower-right) to places where she can lay eggs in vegetation (endophytic oviposition).

Sidebar: Scientific Classification of Damselflies

The following concise explanation of the scientific classification of damselflies is provided to help the reader understand where Argia (Dancers) fit into the bigger picture of the Order OdonataSuborder Zygoptera (Damselflies).

There are four families of damselflies in the United States of America, although only three families occur in the mid-Atlantic USA: Broad-winged damselflies; Narrow-winged damselflies (a.k.a., Pond Damselflies); and Spreadwing damselflies.

Family Calopterygidae is comprised of two genera.

Family Coenagrionidae is comprised of 14 genera. Three genera are common in Northern Virginia: Argia (Dancers); Enallagma (American Bluets); and Ischnura (Forktails).

Family Lestidae is comprised of two genera.

  • Archilestes (e.g., Great Spreadwing)
  • Lestes (e.g., Slender Spreadwing, Southern Spreadwing, Swamp Spreadwing)

There are relatively few genera of Broad-winged Damselflies and Spreadwing Damselflies. In contrast, there are many more genera and species of Narrow-winged Damselflies — more species, including many that look similar, makes this family the most challenging to learn!
