Flower fly

Insecta
Diptera
Syrphidae



I took this photo in my house garden . When seeing it of distant spot I thought about a bee, but observing differences in the flight, antennas, eyes and abdomen, realized that was a dípter (flowers fly , in this case). They used similarity with the bees to move away possible predators.
I used the lens Helios 58 mm in front of my camera.

In Biology, phenomenon that consists of which an organism looks itself like another one, with which does not keep relation, and obtains from it some functional advantage. The object of the mimicry is to deceive the senses of the animals, inducing in them a certain conduct. The known cases more affect the visual perception, but also there are examples of auditory, olfactory or tactile mimicry.

Biologist H. Bates observed that sometimes an inoffensive species was resembled another dangerous or repugnant one and that with this was able to elude the action of the predators. Batesian mimicry is called this phenomenon. He is the one that we observed, for example, in the case of the flies (of the families Syrphidae and Bombilidae) whose aspect emulates the one of bees and wasps.

Bonjour Hernan
La prise enmacro est tres belle avec une jolie composition,L'image pourait êtreun peu plus nette, les couleurs sont superbes.
bravo et merci du partage...JP

Hi Hernan,
Great closeup framing and details seen in this head shot. I like the POV, DOF, and crossed front legs I see.
Perhaps a tiny bit more contrast and saturation would improve it.
Well done & TFS!

Bien sabemos lo difícil que es retratar a estas moscas de las flores de tan cerca y como aquí con excelente nitidez Hernan.
Una imagen que muestra muchos detalles del insecto con un POV muy interesante, que brinda muy buena luz sobre la cabeza, sin producir grandes reflejos.
Bravo!.
Saludos... Ricardo

Ciao Hernán: Otra espectacular captura en jardín compartido. Más que profe de Biología pareces domesticador de insector y animalejos, aunque no quieras tocar a las ranas. Ja! Muy buena tu foto. Felicitaciones.

Un retrato nitido del diptero se ve claramente la trompa succsolamedora, las antenas en la frente cercanas, las cerdas entre los ojos que son elementos de la taxonomia de la familia, complementada por una nota muy ilustrativa desde lo biologico!!!
saludos
