A fungus turns some of the leaves red, mimicking flowers. Insects land on them and carry away spores. Host is Arctostaphylos uva-ursi.

Dark brown rust on Pacific Poison Oak. Appears to be the first iNat record submitted in Oregon, or from anywhere in the Pacific Northwest.

Crushed leaves smelled like vinegar. Very small, growing in a vernally wet area beside Downingia and cryptantha. Many plants have already lost their flowers while some are in bud.

"Kellogg Scale" - found on underside of Grand Fir needles. Apparently the straw color and host are indicative of this species; looks like this is the first record of it on iNat. For reference, see p. 159:
https://essig.berkeley.edu/documents/cis/cis05.pdf
And this species is mentioned on p. 139 of Peterson's "Pacific Northwest Insects" book, which says it "feeds on needles of pines, Douglas Fir, and true fir," and can be separated by color from Chionaspis species (which are white).

Tiny larvae ( <.5 cm ) inside decayed wood, carrying brown orbs, occasionally depositing them. Is it a frass shield like in some Coleoptera larvae? Are they diptera larvae instead??
Bearing a striking resemblance to a slime mold.

This appears to be a green algal form of Peltigera collina. It was growing beside many other P. collina that had the typical darker coloration.

Emerging on the coldest day of the year. Certainly the first time this has been photographed.
Seperation of D. eldoradensis and D. mellifica still needs some work, especially in the Northwest, but I believe this to be the former species based on gall size and morphology.

Clung to the beak of a Whimbrel that was foraging in the seaweed, the bird could not dislodge it, after a couple of minutes the isopod dropped off. The Whimbrel continued to feed with the isopod on board.
