Bug identification (or perhaps a fly?)

I photographed this bug (fly?) on a maize leaf.  The bug was about 4-5mm long.  The photos aren't very clear but any help in identifying it is appreciated.

    There doesn't seem to be any picture with this, so can't help!

        Hmmm, difficult to see details but I think it has the look of a bee of some kind.  Any idea of size?

            Hi again Angie

             

            I can't explain why I think it's a bee, but the one in your picture just has the look of a bee somehow.  Is there a bee expert here who can confirm or deny...?  Some bees aren't very hairy.

             

            Looking up "solitary bees" I got this from http://en.wikipedia.org/wiki/Halictidae

             

            Halictidae is a cosmopolitan family of the order Hymenoptera consisting of small (> 4 mm) to midsize (> 8 mm) bees which are usually dark-colored and often metallic in appearance. Several species are all or partly green and a few are red; a number of them have yellow markings, especially the males, which commonly possess yellow faces, a pattern widespread among the various families of bees. They are commonly referred to as sweat bees (especially the smaller species), as they are often attracted to perspiration; when pinched, females can give a minor sting...

             

             

            And from:

            http://www.moraybeekeepers.co.uk/solitary_bees.htm

             

            "...Common carpenter bees are about 25mm long, but some species are smaller and have black or metallic coloration, like the Ceratina sp. pictured left."

             

            Here's a picture of a carpenter bee, Ceratina sp, from the second site.  I couldn't find the size of the bee in this picture but a bigger species was down as 8mm.  Maybe if you did a search for Ceratina...?

             

             

             

             

            Just found a bit more info from the Brittanica site http://www.britannica.com/EBchecked/topic/96744/carpenter-bee :

            any of a group of small bees in the family Anthophoridae (order Hymenoptera) that are found in most areas of the world. The small carpenter bee, #Ceratina, is about six millimetres long and of metallic coloration. It nests in plant stems, which the female first hollows out and then packs with pollen and eggs. A number of individual cells are placed in a row, separated by thin partitions of wood debris mixed with saliva. The large carpenter bee, #Xylocopa, somewhat resembles the bumblebee but differs in having a nonhairy abdomen and in its habit of nesting in a tunnel
