The distribution range of Anax walsinghami includes Central America and North America. [3] At up to 120 mm (4.7 in) in wingspan and with a typical body length of 89–117 mm (3.5–4.6 in), it is North America's largest dragonfly, [ 2 ] [ 5 ] although exceeded by the closely related giant Hawaiian darner ( A. strenuus ).
The green darner is a large dragonfly; males grow to 76 mm (3.0 in) in length with a wingspan up to 80 mm (3.1 in). [9] [10] Females oviposit in aquatic vegetation, eggs laid beneath the water surface. Nymphs (naiads) are aquatic carnivores, feeding on insects, tadpoles, and small fish.
Common worldwide or nearly worldwide genera are Aeshna and Anax. Anax includes some of the largest dragonflies, including the North American A. walsinghami, Hawaiian A. strenuus, European A. imperator and A. immaculifrons, and African A. tristis, but these are all exceeded by another member of the family, the Asian Tetracanthagyna plagiata, which by wingspan and weight is the world's largest ...
The largest of the earwigs is the Saint Helena earwig (Labidura herculeana), which is up to 8.4 cm (3.3 in) in length. There are no recent records of this species and it is generally considered extinct. [12] The largest certainly living species is the Australian giant earwig (Titanolabis colossea), which is about 5 cm (2.0 in) long. [7]
The black saddlebags (Tramea lacerata) is a species of skimmer dragonfly found throughout North America. It has distinctive wings with characteristic black blotches at their proximal ends, which make the dragonfly look as though it is wearing saddlebags. The black saddlebags is a relatively large dragonfly at about 5 centimetres (2 in) in length.
This species is one the world's largest living dragonflies and the largest in the United States. [3] It typically has a wingspan of 127–143 mm (5.0–5.6 in), [ 4 ] but has been verified to reach up to 152 mm (6.0 in); [ 5 ] reports of considerably greater sizes are unverified and highly questionable.

Adult Canada darners, similar to other members of the genus Aeshna, are relatively large, slender dragonflies, and are predominantly dark brown with paler blue or green markings. [4] [5] Adults are 64 to 73 mm in total length. [5] The thorax has two vertical stripes on each side, the front with a prominent notch and an extension at the top. [5]
The common whitetail or long-tailed skimmer (Plathemis lydia) is a common dragonfly across much of North America, with a striking and unusual appearance.The male's chunky white body (about 5 cm or 2 inches long), combined with the brownish-black bands on its otherwise translucent wings, give it a checkered look.
