Skyline Ridge OSP

KG, PB and I scouted for an upcoming night hike on 9/12/11. We haven’t done a night hike here since 2008, so I was curious to find out what we might see.

We left the lot at 5:45 p.m. I spotted something out of the corner of my eye: a snake skin, left coming out/going into a hole in the ground. Nearby, across from some buckwheat, something with orange, and dark eyes, fled into a hole. It backed up, so I didn’t get a look at it myself.

It was quiet, with no other people around. We got to the intersection at 6:15, and continued through to the chaparral area. We hadn’t decided on a dinner spot, so we checked out the grassy area to the right from the overlook. The grass was flattened, with rabbit and other scat around. We decided to go back to the left side, and eat on the trail that leads past the water tank, arriving there around 7:00.

After dinner and watching the sunset, we headed across the ridge and down the steep trail back to the first intersection (8:00).

We reached the lake bridge at 8:30. We went up Fir Knoll. In the dark, it was a little difficult to navigate since parts of the trail were covered with leaf duff. We found a few scorpions on the trail banks, and heard various owls. We found a katydid and took photos. I decided after we took a few steps to go back and take a lateral view; then I noticed that it was ovipositing.

We spent half an hour there, which made it questionable to continue around the back side of the lake when we finished the loop. We decided to take the lakeside trail back since it was 9:55. We got back to the lot with some time to spare, so we checked out the hole that we’d found previously–no action, though.

Arachnophilia!

A group of ten, including JO, SW and me, met at Monte Bello OSP for our first “official” spider night hike on 10/9/10. (I say official, because as anyone who knows us knows, every hike is a spider hike…) It was a very successful one, albeit more of a meander than a hike. We met at 5:15 p.m. There was a surprising number of cars in the lot (not all ours).

We passed a few juvenile fence lizards on the way to the walnut grove. We found a spider hole in the ground; the hole was perfectly round and had a little silk at least around the inside edge. We marked it to check it on our way back.

There was a Cat-faced Spider (Araneus gemmoides) in the oats/grass near the road, and another nearby. We explained how to find the spider (if not in the web) by following the signal line.

Cat-faced Spider (Araneus gemmoides)

At the sag pond we stopped for dinner. The spider hole was covered over, and I only recognized it because I had looked at a leaf in the photo I took before, which seemed to show some silk purposely attached to said leaf. I don’t remember who told me a long time ago that these silk-lined holes in the ground were tarantula holes, but this one made me question that.

A small dark wolf spider passed by and I captured it while JO talked about the different arachnids. After everyone got a look, we released it. We headed off around 6:30, to get to the “spider patch” before sunset.

There were two Argiope trifasciata and an Araneus gemmoides or two at the patch. Here SW gave a brief overview of how an orb web is made.

We headed uphill and saw a bat or two in the open areas, plus a large owl fly by. Once it was dark enough, we saw a few California Forest Scorpions. When we came to the tree in which another Cat-faced Spider had a web, the spider was very visible but there wasn’t much of a web. On the return, I was behind and saw that she had finished rebuilding it.

We saw a few possible Cybaeus sp., two small Calisoga Spiders along the way, and another 2-3 larger ones. Near the “gravel pit”, we got one into a baggie to look at it more closely. It was very cooperative, and didn’t move while we looked at its ventral side. It was not aggressive at all.

JO spotted a Solifugid near the edge of the trail. We took a look at it also.

We went just past the pit to the edge of the woods, then turned back. I lagged behind for a bit, and found a Jerusalem Cricket and a millipede crossing the trail.

We found two turret spiders, three Harvestmen, another Jerusalem Cricket, and lots of crickets on the trail. Some of us stopped to see if the sag pond burrow was open, and it was. A Calisoga spider was at the edge of the road.

The owls were surprisingly quiet compared to on our scouting hike. The temperature was mild, probably mid-60′s.

The burrow in the trail that we’d spotted on the way in was occupied, and the last section of trail had two small Solifugids.

We were surprised to see headlights as we approached the trailhead; there was a permitted star party going on.

This was a very successful hike as far as finding arachnids. Next time we’ll have to call it a “meander”…

Monte Bello OSP: Arachnid scouting

JO, SW and I scouted on 10/2/2010 for our upcoming night hike. DK joined us.

We started out around 6:10. The temperature was mild. The vinegar weed was blooming. A large raptor that appeared to be a Northern Harrier soared low over the grassland. At the walnut grove, there were remains of a juvenile fence lizard, being eaten by three Western Yellowjackets.

We arrived at the sag pond at 6:30. There were still some Pacific Coast Dampwood termite alates fluttering around. After dinner, we left at 6:53.

The Banded Garden Spider (Argiope trifasciata) found by PB on Canyon Trail a couple of weeks ago was gone, but there was a different individual nearby, plus two Cat-faced Spiders (Araneus gemmoides).

Before it was completely dark, a Great Horned Owl lazily flew from the west to the east, and a bat fluttered by.

Many small Trashline Weavers (Cyclosa) had webs in the woods, mostly low to the ground. These spiders use a stabilimentum as a base for attaching debris (usually prey remains).

There were a lot of very small orb weavers. Another Cat-faced Spider had the beginnings of a web, about five feet up in a tree.

JO found a Cybaeus-looking spider on the dirt part of the trailbank.

The beam of my flashlight revealed two large, round, yellow reflectors–no, they moved! Then there were two more. We stared at them, wondering what they were. JO removed his red filter, and they were just a couple of deer in the woods. I’ll have to remember the red next time I see eyeshine.

Along Indian Creek to the right, we found a smallish Calisoga spider. Near it was a hunting spider.

We were looking for the hidden pond, but I missed the turnoff. DK told us about a pond on the left, which I had not seen before. That was past the other pond, and on the way back we found the one I was actually looking for. There was a Harvestman, and a small tetragnathid, but not enough to warrant the trip down (and back up). We left there to return around 9:15.

Returning on Canyon Trail, we found one small scorpion, a California Forest Scorpion (Uroctonus mordax).

On the Bella Vista Trail sign, a tree cricket sat quietly.

We heard several Great Horned Owls in different places, including the sag pond. Western Screech-owl calls also in different areas entertained us.

The mygalomorph burrow by the sag pond had an occupant, visible after dark.

When we arrived at the lot, there was a group of astronomers and their families.

Southeast Arizona

I’d been wanting to go back ever since I went in 2003, with a local birding tour. Since an opportunity came up with two bay area leaders, I jumped at the chance. Here is our itinerary:

08/06/10

My roommate and I arrived a day before the official start. We stayed at Quality Inn in Green Valley, about a half hour ride from the airport. There is a Walgreen’s across the street, and the median strip has interesting desert plants. Cactus Wrens, White-winged Doves, Gila Woodpeckers, and Great-tailed Grackles were among the motel parking lot birds.

08/07/10

Mission San Xavier del Bac. We couldn’t go inside because of a service. One of the courtyards had a nesting Curve-billed Thrasher.

Sweetwater Wetlands Park. We had a picnic lunch near Brown Mountain in Tucson Mountain Park.

Kinny Road

Arizona-Sonora Desert Museum. I have been there before, but didn’t get to see everything. The same held true this time, partially because I was getting too hot to go where I wanted to go, which was a longer walk.
