Dracaena draco, the Canary Islands dragon tree or drago, [4] is a subtropical tree in the genus Dracaena, native to the Canary Islands, Cape Verde, Madeira, western Morocco, and possibly introduced into the Azores. [5] It was first described by Carl Linnaeus in 1762 as Asparagus draco. [3] [6] In 1767 he assigned it to the new genus, Dracaena ...
Dracaena aletriformis is commonly known as the large-leaved dragon tree. These plants are found in forest in the eastern areas of South Africa from Port Elizabeth to northern and eastern Limpopo. [2] They are also found in Eswatini, [2] but are most common in the coastal and dune forests of KwaZulu-Natal. [3]
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 ...
Trithemis annulata is a robust medium-sized species with a wingspan of 60 mm (2.4 in). The mature male has a dark red head and a yellow labium with a brown central spot. The eyes are red with white spots on the rear edge, and the frons is dark metallic purplish-red.
Having much smaller wing size to body length ratio, the butterflies have a whirring flight, rapidly beat their wings and dart back and forth in a manner reminiscent of dragonflies, their long tails acting as rudders. Male dragontails suck up a lot of water from which the dissolved minerals are filtered and the water squirted from the anus.
The wings have a network of veins; between the veins the wings are generally transparent, but may be partly colored. [1] In most Odonata there is a structure on the leading edge near the tip of the wing called the pterostigma. This is a thickened, hemolymph–filled and often colorful area bounded by veins.
If that famous "Final Destination" logging truck scene already lurks in the back of your mind whenever you're driving on a highway, you may want to sit this one out.
The head is round with a short snout, and the nostrils point upwards. It is active during the day after it has warmed up in the early morning sun. Males have a long yellow dewlap which is shorter in the females. This lizard climbs trees in search of insect prey on the trunks and leaps off when it reaches the top to land on adjoining trees.
