Debris packet
If the debris packed consists of wooly alder aphid flocculence rather than plant trichomes, this would be a larval Chrysopa slossonae. The more pointed abdomen also seems to point more in this direction than the more typical debris-carriers (the bodies of Ceraeochrysa and Leucochrysa are much less elongate).

This one was on a cultivated hazelnut in my yard--
Definitely not within reach of an alder, and I don't think I've ever seen woolly aphids on that or any other hazelnut.

That rules out the easy speci
That rules out the easy species, then. There's also the generalist C. quadripunctata (which is otherwise much like C. slossonae). It's noted as an occasional debris carrier, though I'm not finding much in the literature on the larval debris packet apart from its occasional existence. I've only managed to unearth a single (very poor black-and-white) photo amidst sparse notes on larval biology, though it does show the same facial markings.
