Bee Fly (Toxophora) on Wild Flower

I would like to come up with another species of insect, that is bee fly (Toxophora). Humpbacked is one of the little flies occasionally seen perching on the plant. It commonly lives throughout tropical countries. Look like mosquitoes but it tends to be classified into the order of fly. I found this insect around the bush near the village street. It is quite an impressive and unique fly, which urged me to hunt it down with my smartphone camera. Toxophora or bee fly is the family of Bombyliidae, in the order Diptera. So when I noticed it perching on wild flower, I managed to take shots with my smartphone plus an external macro device but when I was trying to take shot, it finally noticed me and flew away, in the next minutes it came back with calmness. Sometimes I failed to catch but some other time I successfully captured them. While being on the shot, I never thought that they would sting me, and thank for being friendly with me. There are many types of bees around here, and I think this bee is more friendly than others. Indeed, I had to spend much time hunting and waiting for them to calm, that was the efforts to gain better results.
