Meganisoptera is an extinct order of large dragonfly-like insects, informally known as griffenflies or (incorrectly) as giant dragonflies. The order was formerly named Protodonata , the "proto-Odonata", for their similar appearance and supposed relation to modern Odonata ( damselflies and dragonflies ).
Meganeura is a genus of extinct insects from the Late Carboniferous (approximately 300 million years ago). It is a member of the extinct order Meganisoptera, which are closely related to and resemble dragonflies and damselflies (with dragonflies, damselflies and meganisopterans being part of the broader group Odonatoptera).
Articles relating to the Meganisoptera (griffinflies), an extinct order of very large to gigantic insects. The order was formerly named Protodonata, the "proto-Odonata", for their similar appearance and supposed relation to modern Odonata (damselflies and dragonflies).
Meganeuridae is an extinct family of griffinfly in the order Meganisoptera. There are more than 20 genera and 50 described species in Meganeuridae. This family contain the genus Meganeuropsis, which is one of the largest known insects. [1] [2]
The salivary glands (element 30 in numbered diagram) in an insect's mouth produce saliva. The salivary ducts lead from the glands to the reservoirs and then forward through the head to an opening called the salivarium, located behind the hypopharynx. By moving its mouthparts (element 32 in numbered diagram) the insect can mix its food with saliva.
There are fewer differences between the larval and adult forms of Megaloptera than in any other order of holometabolous insects, and their aquatic larvae dwell in fresh water, around which the adults also live. The larvae are carnivorous, and are known to feed on small invertebrates, such as crustaceans, clams, worms and other insects. They ...
Odonata is an order of predatory flying insects that includes the dragonflies and damselflies (as well as the Epiophlebia damsel-dragonflies). The two major groups are distinguished with dragonflies (Anisoptera) usually being bulkier with large compound eyes together and wings spread up or out at rest, while damselflies (suborder Zygoptera) are usually more slender with eyes placed apart and ...
Adults capture insect prey in the air, making use of their acute vision and highly controlled flight. Dragonfly returns to same perch each time it darts out to catch very small flying prey. The mating system of dragonflies is complex, and they are among the few insect groups that have a system of indirect sperm transfer along with sperm storage ...
