This brief report lists only the most important of these resources for the study of the odonata in canada the english term dragonflies here refers to the whole order odonata, which, in canada, includes the suborders zygoptera (damselflies) and anisoptera (dragonflies proper.
Odonata, insect order comprising the dragonflies (suborder anisoptera) and the damselflies (suborder zygoptera) the adults are easily recognized by their two pairs of narrow, transparent wings, sloping thorax, and long, usually slender body the abdomen is almost always longer than any of the wings. Larvae of almost all of the 5,680 species of the insect order odonata (dragonflies and damsel- flies) are dependent on freshwater habitats both larvae and adults are predators the order is relatively well studied, and the actual number of species may be close to 7,000. The present study was based on a scientometric analysis of the research available on the odonata, which aimed to identify the principal trends and gaps in the database on these organisms, compiled online from databases of the institute for scientific information – isi, scielo and journals odonatologica and international journal of odonatology. Order: odonata dragonflies and damselfies the key for odonata can be found in chapter 5 of the guide to aquatic invertebrates of the upper midwest , pages 65-73.
The international odonata research institute is devoted to the study of dragonflies and damselflies and is part of the odonata information network for lots of information and links about odonata, try the oregon dragonfly and damselfly survey. The odonata are amongst the oldest groups of insects known, and are not closely related to any other existing order the largest known insect is the fossil dragonfly meganeura monyi , which had a wingspan of approximately 30 cm.
