Comet Darner
Anax longipes Hagen, 1861

Habitat [-]
This species inhabits a wide variety of (semi)permanent small lakes, coastal plain ponds, abandoned shallow quarry ponds, natural rocky ponds, and sometimes constructed farm ponds. The habitat feature in common seems to be an abundance of floating and submerged vegetation (especially Chara spp.) in eutrophic conditions. It frequents Coastal Plain Ponds with ample shoreline vegetation including Pickerelweed (Pontederia cordata), rushes (Juncus spp.) and Plymouth Gentian (Sabatia kennedyana) (Carpenter 1991). Whether larvae of this species can co-occur with fish is unclear, but the adults are often the dominant species among many other common pond odonates.

Associated Ecological Communities [-]
  • Coastal plain pond
    The aquatic community of the permanently flooded portion of a coastal plain pond with seasonally, and annually fluctuating water levels. These are shallow, groundwater-fed ponds that occur in kettle-holes or shallow depressions in the outwash plains south of the terminal moraines of Long Island, and New England. A series of coastal plain ponds are often hydrologically connected, either by groundwater, or sometimes by surface flow in a small coastal plain stream.
  • Eutrophic dimictic lake
    The aquatic community of a nutrient-rich lake that occurs in a broad, shallow basin. These lakes are dimictic: they have two periods of mixing or turnover (spring and fall); they are thermally stratified in the summer, and they freeze over and become inversely stratified in the winter.
  • Eutrophic pond
    The aquatic community of a small, shallow, nutrient-rich pond. The water is usually green with algae, and the bottom is mucky. Eutrophic ponds are too shallow to remain stratified throughout the summer; they are winter-stratified, monomictic ponds.
  • Farm pond/artificial pond
    The aquatic community of a small pond constructed on agricultural or residential property. These ponds are often eutrophic, and may be stocked with panfish such as bluegill and yellow perch.
