Tangle-veined Fly Family Nemestrinidae

Yeah, those names got your attention didn't they? LOL!! Mine too!! :) Sometimes I think it a good thing I did not study entomology as I would have turned grey trying to remember these names one can hardly even pronounce. LOL!!

In trying to identify insects, I have been told that the only way to do so is under a microscope in some instances. Take a look at these pictures and you will see what I mean. 

 Needless to say they are ALL very difficult to get pictures of as they never seem to settle down for long and just as you creep up to them, off they go again. I think my mother should have named me Patience instead of Joan. LOL!!

Robber Flies

Robber flies vary in size from a tiny 3mm to a large 40mm of which we have about 500 species.
Asilidae diversity can be attributed to their broad distribution, as most species tend to occupy a selective niche. Below: Microstylum sp
As their common name implies, robber flies have voracious appetites and feed on a vast array of other arthropods, which may help to maintain a healthy balance between insect populations in various.
Adults attack wasps, bees, dragonflies, grasshoppers, other flies, and some spiders who could be up to double their size. Below: Neolophonotus sp

Robber flies are particularly abundant in arid and sunny habitats, which are optimal conditions in which to observe their many morphs and behaviors.
Some species are well adapted to desert climates, where they are known to thermoregulate in response to temperature variations throughout the day.

Bottle Fly (Lucilia sp)

It is amazing to find that these pesky critters can be so colorful.
But flies are flies and I can sure do without them in the summer no matter how colorful they are.
