Hi


I spotted some tephritids today and took these photos.
Spectacular and awesome Ceratitis capitata male. A pity that this can be a plague. Sad

indeed, a perfect animal. I used to work on it (taste receptors!) and I regred that had to decapitate several of them. I used to jocke that it was rather C. decapitata actually. You have extracted full beuty from her eyes!

why this female fly has such colourful eyes? Does it help to absorb some wavelenghts that other flies don't see? So the fly can flight among the many leaves of orange fruit tree in darkness? awkward
This uplifts the question: how does a fly really see the world through their eyes?

And what were your conclusions about taste receptors of Ceratitis capitata? Smile

Fruit tephridits have on their tarsi hairs containing extrimely sensitive and selective receptors for their marking pheromone. In Rhagoletis fliees these receptors worked perfectly as dedectors of the pheromone and helped tu find it in chemical fractions but from medflies recording were not clear and obscured so, after some trials we gave up.

decapitata! Smile black humour.

Is true that almost all tephritids flies have very sensitive receptors?

thank you all.

I read in Miguel Tolra's article that flies have a mosaic view! Frown The ommatidia projects very tiny and long tubes that diverge.. hence the mosaic view. But it doesn't tell anything about the reason of colourful eyes in Tephritidae like this one (rthere are other flies that have colourful eyes like Ulidiidae, ect..). Can anyone add more info about this question? Thank you

HI

I use a Canon 30D, Kenko extension tubes (full set), and a Sigma 105 mm EX lens. The flash is a Canon 430 EX. I use ISO 200 (better for macro, usually), and f/11 to f/16 with 1/250, sometimes I use 1/60 and flash off. Find out for Mcyteridae in search, you will find a photo with 1/60 s and without flash.
The EV depends of the light condition. Usually between +0 ev to +1 1/3 . it depends.

may you inform how can we control this plague in orange trees and lemon trees avoiding pesticides?

and why this male fly has such colourful eyes? Any good hypothesis to explain that?

Pretty nice! A fabulous man!

Concerning jumping spiders, I should ask their opinion about tephritids' mimicry. I am afraid, they have no idea of it!
