Maybe? Not sure what plant this is..
Host: Prosopis velutina. Guess of ID is based on other Contarinia species producing galls in the junction of leaflet pairs and the rachis of leguminous trees.
Another tree with the stem bud galls. On willow. Cc @tepary @awenninger
Oligotrophus betheli galls, per Russo's Plant Galls of the Western United States (2021) p. 80 and Gallformers.org https://www.gallformers.org/gall/1750
On Juniperus occidentalis (Western Juniper)
Gall on willow stem? Cc @tepary. Rabdophaga rigidae, the willow beaked-gall midge?

Preserved in EtOH for Cynipini Larval Sequencing Project
Rubber Rabbitbrush; note the conversation associated with https://www.inaturalist.org/observations/153190620. The gall above is the same or similar but on Rabbitbrush, not goldenbush
On chamaenerion angustifolium
Not sure on host plant - Oreocarya sp.?

Edit: Host plant is Oreocarya sp., likely O. flava

I'm assuming this is a gall. On cultivated Q. gambelii.
Gall found on a bigleaf saltbush.
Egg cases of unidentified insect? At first I thought these were galls (because that's what I was looking for), but on closer inspection I noticed the lids—some open, some closed—and one insect that was trapped while emerging. These were found on stems of rubber rabbitbrush (Ericameria nauseosa) near and with, but perhaps unrelated to many larger galls of "Cotton gall tephritid" (Aciurina bigeloviae) (see https://www.inaturalist.org/observations/61430574). In and around a dry wash channel on the alluvial fan 0.4 road mile northwest of the park entrance at Berlin-Ichthyosaur State Park, Ione Valley/ Shoshone Mountains, Nye County, Nevada, elev. 6480 ft.
Two-lobed adult at the 1, 2, and 3 year old nodes of Englemann spruce. Also saw these at Philips Ridge yesterday. Grainy white liquid when burst. Quite sweet tasting and appears to be covered in sweet syrupy honeydew not pitch. Tops of the spruces appear more afflicted and color is off.
I went with this species instead of hemicryptus because my forest insects manual acknowledges this one in the west and not the other. Not certain though.
on what might had been a willow??
Eggs on sunflower
Insect? Fungus? Infection on bromus marginatus
Thanks to @awenninger for reminding me to go check for chokecherry galls at this gas station. Abundant this year. Couldn't find any last year.

Female crawling around on Ericameria nauseosa.
RX10_43304, RX10_43306, RX10_43307, RX10_43308. On Chrysothamnus viscidiflorus (yellow rabbitbrush).
Swollen, discolored fruit on Opuntia sp. With several pupal exuviae protruding. Emergence must have just happened in the last few days.
Large sized stem gall found on a wild raspberry plant. Gall was red in color and looked like almost like a strawberry on the outside. It was covered in thorns just like the stem and was hard to the touch. There were 3 more tiny galls on the stem just below the main mass (visible in the first and fourth pictures). This gall could be caused by a number of things (aphid, mite, midge, fungi, etc.) but I believe that an insect causing this gall is more likely then a fungus.
Gall on Gutierrezia sarothrae, Gall appears to be composed of deformed leaves closely pressed together. With a fresh looking Cecidomyiid exuvia protruding from the side of the gall.
Conical bud gall on Gutierrezia sarothrae. Gall composed of deformed leaves stuck together, and surrounded at the base by a small rosette of leaflets. Superfically similar to galls of Rhopalomyia gutierreziae but I believe this is something different. Collected for rearing.
Interesting bud gall on big sagebrush (Artemisia tridentata)
narrow leaf goldennbush
Younger spruce stand growing in what I perceive to be a younger seral stand (anthropogenic disturbance most likely) that is surrounded by, and mixed in with, an older white spruce stand.

Undescribed gall inducer on Douglas-fir.
Male. Emerged from gall on Ericameria nauseosa on 04/21/2023 on the same day I collected the gall. Gall collected 04/21/2023: https://www.inaturalist.org/observations/156012779. This is a large midge by Cecidomyiid standards, bigger than any I've ever reared or photographed before. The legs are very long as well.
On an Ericameria nauseosa with many Aciurina bigelovii galls.
Never seen this bug before. It is eerily similar to the Birch Shield Bug but shape and color pattern are very different. Maybe different for the sexes? Anyway, pretty and unique so I took my shots:). Any help as always is greatly appreciated.
Four of these emerged from the galls found in pic 5. Host tree Colorado Pinyon. Unfortunately they died before I observed them.
The common nitrogen fixing nodules occurring on the roots of ~20yr old Alnus rubra. These roots were no more than 3-4cm, under the surface of the soil
What are the galls?
Larvae in bud of Sambucus racemosa. Maybe Cecidomyiidae? Asphondylia sambuci galls buds of Sambucus canadensis in eastern North America.
parasitoid of Rabdophaga willow rosette gall maker on Salix pulchra. Pupa with long ovipositor looks like Torymus.
I'm not sure if the gall was caused by an insect or something else. They're not uncommon on blueberry bushes in this area.
I think these galls were caused by the aphids on the opposite side of the leaf, but not positive
I'm not sure if the insect belongs to the galls on the leaves of this Rosa acicularis.
Just a guess about the galls - on Plantago maritima
Infected by a gall insect or leaf miner
