On Oct 16th in my Manhattan neighborhood, this Powdery Mildew fungus on Catchweed Bedstraw (probably * Neoerysiphe galii*, appears to be a first record for the entire New World.
It’s something I’m shocked I’ve never seen in person before, given how avidly I look for isopods – my first sighting of Invertebrate Iridescent Virus 31, or Isopod Iridovirus. Incidentally, also my first-ever virus ID!
Sunday Oct 22nd on Randall’s Island, Neolasioptera convolvuli a new gall (gall midge) for me on Hedge Bindweed. Seems to be quite rarely observed overall.
Not a great image but a cool cranefly from Governors Island on Wednesday 20th Oct, Genus Dicranomyia:
Not a wild plant, and being sold as a cut flower/decoration from a flower farm in New Jersey, but I think it is cool anyway, and very topical, the Ethiopian Eggplant:
For me it was this Eastern Comma I found trying to warm up in the sun around my garden!! I followed it around trying to get a picture of it until it finally landed on his wire a d stayed put.
Interesting question! This one I’m actually not 100% sure about. The color is structural, due to the arrangement of virus particles in a crystalline pattern, so I do believe it begins to change as the host decays. I’ve seen a few cases of dead isopods with iridovirus that show a mottling pattern, though I am unsure if this has something to do with infection severity or just the death of the host. This observation shows this well.
Only Saturday, but I can name it - Odiellus lendlii with 15 observations on iNat so far, species that in literature told to be found in more Southern regions, quite small, sitting on the bark.
Instead of watching the NYC Marathon live at the end of my block, I went to Governors Island along with David Ringer. I was able to show him some things that were lifers for him, and he was able to point out some to me that were lifers to me. Excellent day out, even though a bit chilly.
I got an iNat first United states vertebrate this week , Egg-mimic Darter, a rare, drab fish of clean headwater creeks in a few drainages of the Duck River in Tennessee: https://www.inaturalist.org/observations/100820752
I’ve been looking for this mushroom for quite a while now. Finally spotted some observations for it at a park not TOO far away, but got distracted by a side trip on my way there and then suddenly started feeling like I was coming down with the flu while I was out, and had to head back early. So I was feeling pretty crummy and disappointed as I drove home. Then I really needed to pee, so I found a random pullout on the roadside, ducked into the woods…and there it was!!
