Eristalis arbustorum, the European drone fly, is an abundant Northern Hemisphere species of syrphid fly, originally officially described by Linnaeus in 1758 as Musca arbustorum. The name "drone fly" is related to its similar appearance to the drone of the honeybee. Hoverflies get their names from the ability to remain nearly motionless while in ...
Eristalis tenax, the common drone fly, is a common, migratory, cosmopolitan species of hover fly. [2] It is the most widely distributed syrphid species in the world, and is known from all regions except the Antarctic. It has been introduced into North America and is widely established. It can be found in gardens and fields in Europe [3] and ...
Eristalinus taeniops can reach a length of 11–14 millimetres (0.43–0.55 in). [5] These hoverflies exhibit a bee-like yellow and black coloration (Batesian mimicry) and are often mistaken for wasps or bees.
An example of a well-known hoverfly maggot is the rat-tailed maggot of the drone fly, Eristalis tenax. It has a breathing siphon at its rear end, giving it its name. [6] The species lives in stagnant water, such as sewage and lagoons. [15] The maggots also have a commercial use, and are sometimes sold for ice fishing. [16]
Some of Russia's newer drones appear to feature a modification that could help solve a pressing problem for operators in this war. The drones look to be guided by fiber-optic cables that make the ...
Locomotor mimicry is a subtype of Batesian mimicry in which animals avoid predation by mimicking the movements of another species phylogenetically separated. [1] This can be in the form of mimicking a less desirable species or by mimicking the predator itself. [1] Animals can show similarity in swimming, walking, or flying of their model animals.
[4] [6] Black-shouldered drone flies have opaque, infuscated humeral cells (at the base of their wings), with the rest of the wing entirely hyaline (transparent), except for possibly a diffuse medial spot on the wing. Their hind tarsi are entirely black. Overall, much of the fly is black, though the wings are mostly transparent and the ...
The birds in a truck riddle is a riddle that asks whether a container or a truck carrying birds changes in weight when the birds inside are flying. [1]The television series MythBusters investigated the question in a 2007 episode, testing it both with a box of pigeons and again with a model helicopter.
