I think this is a female midge, a match for the male resting on a dandelion flower blogged about earlier. Note, as with the male, the lack of a probiscus, indicating that this midge does not bite. Note also the lack of plumose antennae, a distinction from the male. As with the male, this is identified by class/order only.
This photo suffers from a lack of strong ambient light. Will have to get a better female midge picture.
