Insect or Invertebrates Identification

Is it moving the wings so fast that we cannot see them?

Yep, hovering over the flower.

[Lisbeth]

I thought so. A "thing" like that has no sense without wings

You are right, but mind you, there are actually some flies without wings who live on bats etc.

[Lisbeth]

Just to make everything more complicated

Nothing near Zululand or even KZN , I am tempted to say we have an undiscribed species

This study on bee-flies in Mkhuze has found only Bombomyia bombiformis and Bombomyia discoidea

Ask an expert is the only way to find out

Bombomyia Africawilda!

Kruger





Also Calliphoridae?

Kruger

Also Calliphoridae?

Yep, but can't tell a genus

There is nothing to look it up, just post it as Calliphoridae with some wise words on the family

A tiny bit of info. on the different make-up of the males' eyes:

Some predaceous insects (robber flies, mantises) may have larger ommatidia on the top portion of their eyes than underneath (it’s called an “acute zone”), which provides some depth perception. Many dragonflies have two acute zones – one to enhance forward vision and the other for upward vision, and a dark area on the top of a dragonfly’s eye may act as sunglasses or may enhance upward vision. In fly species with gigantic eyes, an acute zone makes him more far-sighted, equipping him to recognize a female of the species before she can even see him!

I don't know if this may help explain the stripe of a different color in the eye or not:
A word about pigment cells. The types of pigments present in the eye determine what colors an insect sees; insects that have two or more different types of pigment cells can see in color, and many can see the same colors that humans can (though reds and oranges are not their strong suit). Some insects, in fact, can distinguish colors that humans cannot.

VERY interesting topic, so will study it more later. I do remember that some butterflies see one another as a totally different color than we humans see them- for example one species we see as white, the butterflies see as bright pink due to their ability to perceive a broader spectrum of light than our eyes are adapted for. Anyway.....
