Among the insects, the order Odonata
, popularly known as dragonflies, is a group with low number of species, compared with other groups of insects (Buzzi, 2013), characterized by present aquatic nymphs and terrestrial flying adults (Corbet, 1980).
URBAN RURAL ORDER ODONATA
Suborder Zygoptera Family Calopterygidae Hetaerina sp.
CUTE DAMSEL | Damselflies are insects |in the order Odonata
The genus Cloeon was the only representative of the mayfly families that occurred on a regular basis and the damselfly Ceragrion, also a member of the order Odonata
, was often present as well.
Steve Brooks of The Natural History Museum entitled his review (Brooks 2009) of this book, "Aren't dragonflies great study organisms?" His enthusiastic statement sums up the purpose of the volume: to review the use and value of dragonflies and damselflies (Order Odonata
) in the development of ecological and evolutionary theory.
Both have large multifaceted eyes and belong to the order Odonata
(hence the name "odonates"), but there is an obvious difference in the way they hold their wings at rest: dragonflies hold their wings open fiat horizontally, perpendicular to their bodies (see photo above), whereas damselflies hold their wings over their backs, either closed (see photo below) or in a v-shape.
Coenagrionidae is a cosmopolitan family and the largest in the order Odonata
with about 1100 described species.
Dragonflies, and their smaller cousins, the damsel flies, are members of the insect order Odonata
. True dragonflies belong to the suborder Anisoptera, while damselflies belong to the suborder Zygoptera.
Even though dragonflies (Order Odonata
) are commonly observed perching on pitcher hoods, we have never observed one captured in hundreds of pitchers examined (J.
Dragonflies belong to the order Odonata
, which includes dragonflies (suborder Anisoptera) and damselflies (suborder Zygoptera).
