This moment I Find When I was in the garden with my father on tanggl March 11, 2012 at 10 am I found a Robberfly (Asilidae) are running neck males chase the females robberfly, Robberfly the Insects in the Diptera family Asilidae are commonly called robber flies. The family Asilidae contains about 7.100 described species of robber flies have worldwide.All stout, spiny legs, a dense Moustache of bristles on the face (mystax), and three simple eyes (ocelli) in a characteristic depression Between Their two large compound eyes. The mystax helps protect the head and face when the fly Encounters prey bent on defense. The antennae are short, 3-segmented, Sometimes with a bristle-like structure called an arista.The short, strong proboscis is used to stab and inject saliva containing neurotoxic Victims with proteolytic enzymes and the which paralyze and digest the insides; the fly then sucks the liquefied meal through the proboscis. Many species have long, tapering abdomens, Sometimes with a sword-like ovipositor. Others are fat-bodied Bumblebee mimics. Adult robber flies attack other flies, beetles, butterflies and moths, Various bees, ants, dragon and damselflies, ichneumon Wasps, Grasshoppers, and some spiders. . And the male managed to attract females and those with a Married perched on leaf weeds, but when I approached to my photos, but it flew straight to the dry branches rather high, but what happened? there appear Robberfly Robberfly Females Males perch while hanging while still in a state of marriage. What a wonderful moment, I was without a doubt memotrek insects in this marriage with my camera the Olympus E-410 with Sigma 105 macro lens with aperture f/10 Focal Length with the length of 105mm and the background was quite far away so I got a decent background smooth and neat when it blows hard enough so that robberfly dependent and dry tree branches swaying so I use Shutter Speed 1/125 sec with Iso 400 to freeze the movement caused by wind, so I photographed these insects without doubt more more of 30 shots while they have not run away because I think they do not cukum comfortable with this position so that they will run away. But after 30 minutes I saw them still survive mating in a position like this. I also gained the next day as usual into the garden and there are many robberfly who marries a dependent position, and when I touched them they did not fly even had time to move the leaves to the wedding of my hand. And I also gained an impression:A. Robberfly (Asilidae) can marry more than 30min2. Their mating positions in various positions as he was eating, while married and while perch3. When they were married there in any position and any disruption to marriage they remained until the end unless there is something really dangerous to them.eating, while married and while perch3.
