Sadly poor photos, but quite interesting nonetheless. MA Peterson (PNW Insects) illustrates this species, which he states to be separable from similar species by the bands on the tarsi, seemingly visible in these photos. See last image where I have adjusted contrast to show a very white 2nd joint from the body on the rear legs. (I used the on-camera flash for these photos, which brightened the entire legs). Although Peterson lists this as common, even in cities, there are only 2 BugGuide records for Oregon, in May and June. This December photo (assuming ID is correct) extends their active range significantly, although BugGuide Info states they overwinter.
Apparetly the 'clouds' visible in these photos are associated with the antennae? See for a nice view of these antennae. But quite different here, looking somewhat like a dew-covered spider web. It was relatively sunny and warm on this late fall day, so that is unlikely. The blurry photo (also saturating on-camera flash) shows these 'clouds' to be present symmetrically on or near both antennae. The eyes are pretty clearly blue, which led me first to search crane flies but with no luck. Then searching midges led to the nearby mosquito page in Peterson. I'm glad this particular insect was just one more sucking on these English Ivy berry buds, rather than sucking on me. Peterson states it to be a vector for all things evil. But that they also feed on sugars which are apparently secreted even by the berry-forming buds which attract a very wide variety of insects, late in the season. as photographed this fall.
P.S. Re: the Blue Eyes. Checking crane flies again I discovered ; interestingly similar, but this Crane Fly has wings much longer than the body.
