Fly dining on aphids? - Lucilia sericata

Fly dining on aphids? - Lucilia sericata
Sunnyvale, Santa Clara County, California, USA
October 4, 2007
This looks similar to another fly tentatively identified as a Green Bottle Blowfly in Family Calliphoridae, Genus Lucilia. I'm not sure what they eat, but it looks like this one is eating aphids.

Not eating the aphids:-)
Aphids secrete a sweet, sugary waste product called "honeydew" in copius amounts, such that it literally rains down out of the host tree. This substance is craved by everything from flies to bees, wasps, beetles, even butterflies. So, 'that' is what this fly is lapping up here.

 
I knew that ants did that but...
...I have been maybe a little preoccupied with the impression that every thing in the insect world seems to be in the act of either eating, or being eaton by some other insect!

In this case I would have been just as happy it it was eating the whole aphid!

Lucilia looks right to me
Nice series, Mac.
