Here's a sneak peak at what I'll have coming next month for my annual Audubon sale; 2 of the 4 insects included in my "Nature's Wonders Flies" (a Giant Robber Fly and common Housefly). The twig is from my "Songbird ReMix Paridae of the World". The Giant Robber Fly or "Assassin" fly occurs in all zoogeographical regions except Antarctica. It prefers regions that are in warm climates; tropical or subtropical and arid or semi-arid regions tend to have the greatest variety of species, followed by areas where rainfall is highly seasonal. It can be found in lesser numbers in the Northern Hemisphere in the tundra. It attacks a very wide range of prey, including other flies, beetles, butterflies and moths, various bees, ants, dragonflies and damselflies, ichneumon wasps, grasshoppers, and some spiders. They seem to do so irrespective of any repugnatorial chemicals the prey may have at their disposal. When attacked or mishandled by humans, they do not hesitate to defend themselves, using their proboscis to inject saliva with which they deliver intensely painful bites.
