The Zygoptera, or Damsel-Flies, of Illinois [PDF]

open access: yesIllinois Natural History Survey Bulletin, 1917
The order Odonata includes all insects known as dragon-flies in the broad sense of the term. The adults are characterized by the possession of four membranous, net-veined wings which are of nearly equal size. The mouth-parts are fitted for biting and the

Ecological and faunal analysis of dragonflies (Odonata) of suborders Zygoptera, Caloptera in Republic of Ingushetia [PDF]

open access: yesE3S Web of Conferences, 2021
In this work, we adhere to the systematics proposed by the school of odonatologists B.F.Belyshev, that is, the order is subdivided into three suborders: Anizoptera, Zygoptera and Caloptera.

Evaluating Conservation Corridor Success for Rare and Common Dragonflies Using Zeta Diversity. [PDF]

open access: yesEcol Evol
This study applied the zeta diversity framework to evaluate how conservation corridors in South African timber plantations impact dragonfly assemblages, finding that corridors function similarly to natural habitats. The research findings showed that dragonfly species richness was higher in corridors than in natural areas, consistently declining with ...

Unexpected Evolutionary Divergence of Tachykinin-Positive Neurons Innervating the Central Complex in Hexapods. [PDF]

open access: yesJ Comp Neurol
The central complex is a group of midline‐spanning neuropils in the brain of insects with a key role in goal‐directed orientation and navigation. Immunolabeling in 25 species, ranging from bristletails to flies, shows that neurons containing peptides of the tachykinin family of neuropeptides are present in most species studied.
