The wildlife was not particularly interested in waiting for anyone to give the go ahead for the event to begin however. In the rolling hinterlands many of us were able to observe a pronghorn frozen in place under the dry, burning sun, well before we reached base camp.

| Additionally, a roadside stop on the drive up procured a new late-summer buckwheat for me, Eriogonum baileyi.|

The first highlight I'd like to post is a new ladybug for me, Exochomus aethiops. It comes from the notoriously difficult subfamily of Chilocorines, which often cannot be identified without the specimen, but this guy is relatively diagnostic in California fauna, if only for its complete lark of markings.

the high domed shape and shine rule out other species.
A new odonate for me, and a species that had been on my wishlist for some time, was the desert firetail, Telebasis salva, common around stagnated ponds just below the north and eastern hillsides. Others were able to see the dragonfly equivalent of this damselfly, the cardinal meadowhawk Sympetrum illotum, but they didn't show for me!

The lower portions of the canyon held great numbers of two more buckwheats I had not recorded before, Eriogonum wrightii and Eriogonum rosea. Eriogonum wrightii was a larger shrub with bigger flowers:
Yet despite its size it was still an easy plant to miss if you weren't paying attention:
In contrast Eriogonum rosea's colour made it a little easier to notice:
A curious find in the lower wetland was the European species Mantis religiosa. Though not uncommon since its introduction in California, it is supposedly absent from desert and dry regions, so this was an interesting record for the ranch property. The species is easily distinguished by the black spot on the front legs (which is usually but not always is adorned with a white bull's eye). The wetland itself held a number of plants that were new for me including scratchgrass Muhlenbergia asperifolia, Clematis ligusticifolia, Erigeron breweri, as well as the venus thistle Cirsium occidentale var. venustum.

We met back several times to share finds. One interesting spider was this nice example of Phidippus comatus, a spider that, as is typical of the jumping spider group, would rather sit perfectly still and stare at you than run away. Before night fell it was clear that the canyon was not going to spare us the curse of the eternal wind. It was above 20 mph within less than an hour, and above 30 mph before it turned completely dark. Despite this it was far from unsuitable conditions for wildlife hunting.
We were treated to some nice early nocturnal species, though the wind made it virtually impossible to attract any proper moths or insects to the sheet. One bonus was seeing Ateloplus luteus on the desert track, an incredibly poorly known species that has not been photographed before, all thanks to Jeff Cole's oatmeal trails! The male seems to live up to the name luteus, while the females are greyer in colouration. Another bug, stripe-tailed scorpions Vaejovis waeringi, were not rare in the darkness, and we were able to demonstrate its bioluminescence under blacklight. One of these scorpions decided it was going to live directly under the center of my tent!

I saw a desert pocket mouse beside the path just before I decided to turn in for the night. I do wish I stayed up longer to scope out some neat nocturnal life. It would have been far more lucrative to spend more time doing that as opposed to trying to sleep in the high gusty winds of Sacatara Canyon which was a force in the ears as well as against anyone trying to stand still. The next day we spent the morning out again before packing up for the day. There was a period to pull in some final ticks for the event during that time, starting with the unusual leafhopper Cuerna yuccae which occurs only on joshua trees.
I was additionally able to attend a short outing with Jeff Cole which landed some new grasshoppers for the range list. Not to mention many of the species were new for my personal list as well, including Trimerotropis californica, Melanoplus marginatus, Aulocara elliotti and Derotmema laticinctum.

We also encountered some more common species in California, but a few were good crowd-pleasers nonetheless, especially Dissoteira pictipennis:
Another nice species was the hedgenettle stink bug, Cosmopepla conspicillaris, which as its name suggests is specific to Stachys. The lower plants here were home to small groups of another grasshopper which suffered from dull colouration, but made up for it with a great name: Melanoplus devastator.
Two of the best spiders were the shining silver Argiope trifasciata, and a really nice example of the uncommon genus Titiotus sp. Perhaps my biggest mistake of the trip (besides not understanding how tents work) was not photographing the epipygium of this spider. There are three identical species only separable from this feature, and two of them are completely endemic to this area. I'll never know which one it was! All three species lack photographs and information on the internet. Hopefully future excursions onto this property will nail what species occurs here specifically, but that may well be past my lifetime.

|Titiotus cf. icenoglei. At least the rainbow iridescence on the base of the legs makes|
up for its lack of species identification.
The final awesome find of the day was this guy on the path. Given that I had been stuck on 4 species of reptiles in North America for a good two years, it was fantastic to finally find a fifth.

We spent the final hour sharing observations and potted specimens, and looking back on the experience and how it could have been improved. For me all I could have said was that, as usual, I wish I spent my time a bit better! But nonetheless a tremendous excursion with over 50 new species for my personal list, and a big thanks to the "big three" Scot Pipkin, Laura Pavliscak, and Mike White for organizing the event and sharing their knowledge.
PS, turn the wind dial down next time. Anything above 20 is too high :)
