Lots of Bract Galls and a Glimpse of Some American Goldfinches, 06-30-22

I got up around 5:20 this morning and headed out to Stone Lakes and Bruceville / Desmond Roads near the Cosumnes Preserve. First though, I had to fill up the gas tank in my car. Cost me $94! Guh! [Thank you for helping to pay for gasoline, Matt.]

I wasn’t looking for anything in particular; I just needed to get outside while it was still cool, before the heat showed up. It was about 58º when I got to Stone Lakes, cool and breezy.

The bract galls on the rose bushes were the standout there. There seemed to be more of them visible than the last time I was out there. I also found some Spiny leaf galls and Rose Blister galls on the plants…and what I think is a new-to-me gall: the galls of the Rose Stem Galler wasp.

The cottonwood trees were showing off lots of petiole galls, but only a very few leaf galls. There were no galls on the oak trees except for some large oak apples. I wonder if the dearth of smaller galls wasps has made more room for the larger ones.

There still aren’t as many insects around as I would like to see. I found a crab spider, and some Yellow-Faced Bumble Bees, a few Boxelder Bugs, and a new-to-me Say’s Stink Bug (in a lovely bluish-green color). But not nearly as many bees, wasps, and other pollinators as there should be.

Among the birds I saw a few Killdeer, Song Sparrows, Tree Swallows, House Finches and Kingbirds there, but not much else. One of the Song Sparrows was deep in the midst of a molt and had no tail feathers. And I think the Red-Winged Blackbirds were all in the middle of caring for their babies, so I could hear them fussing among the tules, but only saw one or two of the actual birds. One of the female blackbirds stopped near me, griping through a closed beak that was full of insects.

I was happy to see the stands of narrowleaf milkweed now in bloom, but sad to see there were no insects on them – not even aphids. No evidence of Monarchs anywhere.

I then headed over to Bruceville and Desmond Roads and drove around there for a little while before heading home. A couple of surprises was seeing a Ring-Necked Pheasant in one of the fields, and a smattering of Lesser and American Goldfinches feeding among the tarweed and star-thistle.

When heading back toward the freeway, I saw a family of kestrels on the top of a telephone pole and line. It looked like the parents were teaching their fledglings how to fly. So cool.

So, not a great deal of diversity, but I did see a few things. And, oh my gosh, I attracted sooooo many ticks! I stopped counting at 25. At one point, I lifted up my shirt and there were six of them attached to my stomach! *Shudder*

I was out for about 6 hours, but about 2 hours of that was just driving back and forth from the destinations to the house… so 4 hours of naturalist work. This was hike #38 of my #52HikeChallenge for the year.

A Crabby Baby Scrub Jay at Effie, 06-26-22

I got up around 5:00 AM and got myself ready to head out to the Effie Yeaw Nature Preserve for a walk before it got too hot. [It got up to 101º by the afternoon.] I haven’t been to the preserve in quite a while, and I was hoping to see some deer and some galls on the oak trees. The oak trees are still completely devoid of galls (beyond the ubiquitous Oak Apples), but I did see a few deer: young bucks in their velvet at the beginning and end of my walk.

On the Showy Milkweed plants near the nature center, I found a large katydid, several ladybeetle nymphs, a Green Lacewing, and lots of Oleander Aphids. It looked like there was some kind of worm or larvae on the “neck” of the lacewing, but I couldn’t find anything on what might parasitize them. More research needed. 

Also on the Showy Milkweed, I found a bee that had died because it got it’s foot stuck in the flower.

“…If you’ve never seen this, this is how it works: milkweed produces pollinia, a sticky structure or packet of pollen grains originating from a single anther (male part). During the flower’s complex pollination process, the mass is transferred as a single unit and looks like a yellow wishbone dangling on a honey bee’s legs or other parts of her anatomy. It’s a devious way for the milkweed to force insects to help them reproduce–in exchange for the sweet nectar reward… But it’s a trap, a floral trap. Sometimes you’ll see frenzied bees struggling to free themselves from the sticky nectar trough. They are not always successful. Return to the scene of the grime and you’ll see insect parts or whole insects trapped in the sticky mass. Dead…”  [Kathy Keatley Garvey]

I came across a very ant hill, of large black Harvester Ants. It looked to me as though the ants were carrying stuff OUT of the hill rather than carrying it in. I wondered if they were doing some late spring cleaning… or relocating the nest.  When I returned to the spot at the end of my walk, the ants were nowhere to be seen. So interesting.

I was intrigued and amused by a young fledgling Scrub Jay who, although he was certainly big enough to get his own food, he demanded that his parent feed him. I saw a couple of instances when the parent brought a tidbit and laid it down on the ground in front of the fledgling, and the fledgling picked it up, then put it back down again – and started crying to be fed. Hah!

Closer to the edge of the river, there was a Red-Winged Blackbird who was attacking people, including me. He’d swoop down out of an alder tree and go for your head. I don’t know if he was trying to establish a territory or protect a nest… but I thought that was such place for him to be. I’ve never seem the blackbirds down by that part of the river before.

I also saw both California and Spotted Towhees along the trail, including this Spotted Towhee who sang for me:

The river was actually a little higher than it had been during salmon season, and I saw quite a few plants partially submerged – like gold wire and centaury. 

Also along the edge of the river I was happy to find one of my favorite insects: the Big-Eyed Toad Bug. They hop around like tiny toads and can swim through the water as well as move quickly on land.

“…Toad bugs may walk rather rapidly, or they may hop, toadlike, along muddy, sandy, or rocky shorelines of streams or ponds…The family name, Gelastocoridae, means “laughing bug” or “ridiculous” or “funny bug” (gelasto means “laughing” in Greek). Somewhere, sometime, an entomologist was certainly amused by these minute, weird-looking, bouncy insects. When you see them, you may decide that they’re cute, as well…” [Missouri Dept. of Conservation]

“…Gelastocoridae are riparian insects, generally found at the margins of streams and ponds, where they are predators of small insects. Gelastocoridae catch their prey by leaping on top of them and grasping them with their modified front legs. Adults lay their eggs in sand. Nymphs of many species cover themselves with a layer of sand grains. Apart from the no doubt considerable physical protection that the armor affords them, the layer of sand renders them effectively invisible on the ground unless they move at the wrong moment. Many Gelastocoridae species can change their coloration to match their habitat…” [Wikipedia]

There were a lot of the tiny “blue” butterflies flitting around the rocks by the river, and further inland I saw quite a few California Pipevine Swallowtail butterflies feeding among the trees and some of the thistles in the fields. Most of the pipevine is gone by this time of year, so I’m hoping they’ll be able to find somewhere to lay their eggs…

I found Crown Whitefly eggs and nymphs on the underside of live oak leaves.

“…Typical whitefly life cycle of eggs laid over the surface of the leaf hatching to the mobile first instar nymph. As this moves to the second instar the legs are lost and the insect becomes sessile, feeding in one place through the next nymph stages and the pupa. Identified most easily by the pupa, which has a black oval body surrounded by wide lateral sheets of white wax, wide white wax sheets protruding from the front and rear, and a vertical dorsal ‘crown’ of white wax arising from the top of the body…” [PestWeb.com]

A Day in Yolo County, 06-22-22

I got up around 5:00 AM this morning and got the dogs fed and pottied before getting myself ready to go out on outing with my friend Roxanne. We ended up going up to Woodland with stops at County Road 22 and the Ibis Rookery, and then circling around to Davis afterward. So it was a Yolo County day.

It was another hot day (got up to 100º), so we knew that wherever we went, we’d have to cut our outing a little short to beat the heat. When we got to Woodland, we went down Road 22 which parallels the freeway. There’s a slough there that usually has some water in it, and I knew there were rose bushes, buttonbush, tules, willows and other shrubs long there that I hoped would present us with some insects, galls and spiders.

What originally caught my attention, though, were spiny clusters of sort of prickly burs on plants all along part of the road. I at first thought the clusters were a kind of gall I’d never seen before and I was super-excited about that. Then Rox calmed me down and we studied the plant more closely; no thorns, burs were like cocklebur but in bunches, compound leaves,  the leaves and stalks were slightly sticky (glandular)… I took some photos and posted them to iNaturalist. The plants were Wild Licorice! I’d never seen that plant before, so even though it wasn’t a new kind gall, it was a new plant I could add to my species list for the year.

We saw cities of Spotted Orb-Weaver Spiders, but none of the spiders were very big yet. Give them a few weeks; they’ll bulk up. I also found one crab spider. But overall the showing wasn’t as impressive as I thought it might be.

We did see galls on some of the willows (which I think were Interior Sandbar Willows because that’s the species most often associated with ag land in that area): a few pinecone galls and some stem galls.

On the rose bushes we found a few Spiny Leaf Galls and some fat Leafy Bract Galls. I also found a few midvein galls on the leaves of some of the bushes. I don’t know if they were “aborted” spiny galls or something else. I found them on several different bushes, but they were all the same: brown, hard, on the midvein, and about the same size.

There was one other rose bush that looked all but dead, but with a few leaves at the very top of the otherwise gray leafless canes, and some green canes sticking out of the bottom of it. At the base of that were tufts of “witch’s broom”: tough but pliable filaments in clusters attached to the stem. This is evidence of Rose Rosette Virus (RRV). Very cool. I was hoping to find some Mossy Rose Galls on the bushes, but I didn’t see any.  Definitely worth going back in a week or so to see how things have developed.

“…Rose Rosette Disease (RRD) is a devastating disease of roses. It makes the rose unsightly because of abnormal growth of the rose plant tissue. Symptoms such as witches’ brooms, excessive thorniness, enlarged canes, malformed leaves and flowers are associated with this disease. This disease has been reported since the early 1940s but only in 2011 did research demonstrate that it is caused by a virus, aptly named the Rose Rosette Virus (RRV). Diagnosis of RRD prior to 2011 was primarily done based on observed symptoms and the presence of the eriophyid mite that is believed to be the vector of RRV…” (https://roserosette.org/

There was a small stand of Showy Milkweed plants in another spot on the roadway, but we didn’t see any Monarch eggs or caterpillars. In fact, the plants were pretty much devoid of all insects – which freaks me out.[READ THIS article about the collapse of insect populations in California.]

CLICK HERE for the full album of photos.

Showy Milkweed, Asclepias speciosa

There were two dead animals on either side of the road at one spot: a raccoon and a deer. The raccoon carcass was pretty well gone-over, but there was a lot left for the vultures and other critters on the deer carcass. I know some folks think its gruesome that I take photos of the dead things, but death is all part of the cycle…and it’s interesting to me to see how the carcasses are broken down by the scavenging cleanup crews.

We then drove over to the former Ibis Rookery to see what might be there. There were may three or four Ibises sitting on nests in the main settling pond, but they were so far away, there was no way I could get photos of them. That is sooooo disappointing.

There were a few Barn Swallows flitting around the fence lines, and a flock of American White Pelicans fishing together very near the edge of the pond. I think they were actually scooping up frogs along with little fish. In the video snippets I took, I thought I could see frogs jumping away from them.

Along another side of the pond there were some Black-Necked Stilts, some of them wading, some of them swimming, and some of them screaming loudly and doing this odd repetitive wing-flapping thing.  I also saw one fly up onto the road and sit down, like it was sitting on a nest, then got up and flew off in another directions.

I looked up these behaviors in Cornell, and found the following: “…During Wing-flagging Display, calls resemble a warble… Distraction displays include Wing-flagging Display (while both sitting and standing), [and] False Incubation Display… In Wing-flagging Display, wings are partly extended and raised up and down; often only one wing at a time is extended, and the individual may sit, stand, or alternate between sitting and standing while performing the display. In False Incubating Display, individuals crouch on the ground as if incubating eggs, then rise and move to another spot and sit again…”

There were several different species of dragonflies buzzing around, but no one stopped long enough for me to get a photo of them. Dangit! I did get to capture some photos of a pair of damselflies “in wheel”, though, and that’s always cool.

We saw quite a few cottontail rabbits and one young jackrabbit while we were heading out. 

A drive past the smaller settling ponds yielded little because all of the birds were outside the range of my camera. (Sooooo frustrating!) I did manage to spot and get some VERY blurry images of a Redhead Duck, some Rudy Ducks, and a pair of grebes. The only fairly good photo I got from that side of the road was of some Black-Crowned Night Herons standing on the rocks along the edge of the pond.

After that, we drove into Davis for some brunch at the Crepeville restaurant. On the way, we passed fields of safflower and stopped at a sunflower field to get some photos. Oddly, only every third row or so of the sunflowers were in bloom. We wondered if those were a different species than the others.

By the time we got back to the house, it was100º F outside – and completely overcast. So weird. I think we were getting the edge of a passing monsoon. We were out for about 6 hours.

The Usual Suspects at Gristmill, 06-19-22

I got up around 5:30 this morning so I could get outside for a walk before the heat of the day came on. Walking in the summer is harder for me because I have to get up earlier to catch the few hours of comfortable temperatures… and going out early means I miss a lot of the insects that don’t come out until it gets warmer. Grrrr.

I went over to the Gristmill Recreation Area and didn’t see much of anything that I haven’t seen already.

The galls on the willows are getting more impressive and easier to see as the larvae inside of them grow. I did find one that didn’t look like others I’d previously seen. I don’t know yet if it’s a “new” gall or just an early iteration of a gall I’ve already seen. I’m not seeing any new galls on the oak trees yet.

CLICK HERE for the full album of photos.

I saw a few Black-tailed Jackrabbits around, and a couple of them let me take their pictures. No such luck with the California Ground Squirrels, though.

I watched a male Downy Woodpecker hanging around the hole to what I assumed was a nesting cavity. But I don’t think it was HIS nesting cavity. I saw a beak poke out toward him that looked “heavier” than a Downy beak would be… so I’m not sure what kind of bird was in there. I later saw the woodpecker going through the leaves of nearby trees collecting insects.

There were a lot of White-Breasted Nuthatches climbing the trees all around the trail looking for food. And I saw a Spotted Towhee stuffing its face with elderberries before flying away.

Elsewhere on the trail I found a Bewick’s Wren fledgling that was looking pretty rough, but that didn’t stop it from singing.

I walked for about three hours and then headed home. This was hike #36 in my #52HikeChallenge for the year.
