The dominate dragonfly family was Libellulidae, which accounted for 18 of the 30 total species, followed by Aeshnidae (4 spp.
The dragonfly species composition in marshes primarily consisted of Libellulidae (skimmers), while Libellulidae, Aeshnidae (darners), and Gomphidae (clubtails) were common in oxbows and sloughs.
They want to learn how to tell their Aeshnidae
from their Gomphus, and perhaps coming away with a better understanding of the life of odes.

Macroinvertebrates were collected from eight taxonomic groups: one suborder, Zygoptera, and seven families, including the coleopterans Gyrinidae and Hydrophilidae, odonates Aeshnidae and Libellulidae, and hemipterans Belostomatidae, Corixidae, and Notonectidae.
Concentrations of mercury in Aeshnidae were significantly higher than Libellulidae (P = 0.
This study examined the holdings from Abilene Christian University Natural History Collection (ACUNHC) and Hardin-Simmons University Invertebrate Collection (HSUIC), which provided records for 23 species of anisopterans, of which eight are from the families Aeshnidae
, Corduliidae, and Libellulidae.

Anaxjunius (Drury): A8, C2 Basiaeschna janata Say: B3, C4, D1, D2, D8 Boyeria vinosa (Say): A2, A6, A9, A10, A12, A13, B5, C2, C3, C5, C7, C10, D7, D9, D10, D13 Nasiaeschna pentacantha (Rambur): C2 Family Corduliidae Somatochlora spp.
The 25 species represented 4 families (suborder Anisoptera: Aeshnidae
, Libellulidae; suborder Zygoptera: Coenagrionidae, Lestidae).

The Family Aeshnidae (darners) was collected at FWS1, 3, 4, and 5.
Most Aeshnidae larvae inhabit standing waters, especially weedy permanent ponds, marshes, and the shallows of lakes, and a few inhabit streams; Corduliidae also occupy stream debris, and Libellulidae are occasionally found along stream margins (Hilsenhoff 1991).
