This was our last Project Dragonfly Observation of the Week for 2022. Thank you to everyone who has joined this project! It has grown to over 300 members and 213 species of dragonfly and damselfly were observed. Citizen science helps wildlife and so does habitat conservation! Learn how you can help save nature's dragonfly nurseries.

Observation of the Week: common green darner

This week's feature is a common green darner, photographed and logged by iNaturalist user joebartok in Ontario. The common green darner is one of 16 migratory dragonflies in North America. Like monarchs, these dragonflies embark on a multi-generational migration, where the generation that returns to Canada in spring are the grandchildren of the ones that left in autumn.

Qui mange qui?

Les libellules sont un élément essentiel de la chaîne alimentaire dans les écosystèmes des milieux humides. Les larves des libellules sont des prédateurs en embuscade qui dévorent tout : autres larves d’insectes, têtards et petits poissons. Les larves sont aussi des proies, qui nourrissent les gros prédateurs aquatiques comme les poissons.

Les libellules adultes attrapent généralement leurs proies en plein vol : elles les captent avec leurs pattes. Les différentes mouches constituent l’essentiel de leur régime alimentaire. Les libellules vont même jusqu’à s’entredévorer. Elles sont aussi capables de se nourrir d’espèces plus grosses qu’elles. On a même observé une libellule dévorer un colibri.

Les nombreux liens entre prédateurs et proies sont bien connus, comme ceux que nous avons évoqués ci dessus. D’autres pourraient vous étonner. Répondez à notre jeu questionnaire Qui mange qui sur la faune des milieux humides pour mettre à l’épreuve vos connaissances (et peut être apprendre des faits nouveaux)!

Who eats who?

Dragonflies are an important part of the food web in wetland ecosystems. As larva, they are ambush predators, eating many things, including other insect larvae, tadpoles and small fish. They are also prey, feeding larger aquatic wildlife like fish.

Dragonfly adults typically catch their prey while flying by grasping them with their legs. Various flies make up much of their diet, and they’ll eat each other, too. They are also capable of eating species larger than themselves. There is even evidence of a dragonfly eating a hummingbird.

Many predator-prey connections are well-known, like some of those listed above. Others may surprise you. Try our Who Eats Who wetland wildlife quiz to test your knowledge (and maybe learn something new)!

Observation of the Week: ebony jewelwing

This week's feature is an ebony jewelwing, photographed and logged by iNaturalist user awaysick in southern Ontario. Their brilliant metallic green bodies flash sunlight as they flit around streamside vegetation and their large black wings quickly attract attention. They are also short-lived, usually only living as a flying adult for about two weeks.
