Your fly is a Brown Lacewing, not a true Fly. I can't really see enough detail of the "lumps" to hazard a guess as to what they are.

Lacewing affliction

Thanks Matt for ID. Unfortunately, I don't have clearer photo of the 'lumps.'

The lacewing has become trapped in the hairs on the leaf surface. If you blow up the picture you will see they are hooked. Some plants have hooked hairs as a defense against herbivorous insects, ironically in this case it has caught a lacewing. A common species of plant with minute hooked hairs on the leaves is the common or garden runner bean.
