Two-Horned Galls and a Beetle with a Hairy Chest, 07-11-19

Around 5:30 this morning, I headed out to the American River Bend Park for a walk. It was in the high 60’s when I got there and heated up quickly; around 71° when I left.

 I didn’t have an agenda in mind and was just watching for whatever Nature wanted to show me. I ended up finding a few galls on the oak trees, including one I’d never seen before. I’d seen photos of them but had never seen one “live”. It was a Two-Horned Gall of the wasp Dryocosmus dubiosus. Coolness. They’re found on the underside of the leaves of Live Oak trees, usually along the median vein. Also found the big Oak Apple galls, tiny Pumpkin Galls, and some Goldenrod galls.

In the water fountain near the restroom, I found a large beetle lying on its back.  It was about an inch long and really kind of “hairy”. It had lost one of its antennae and was dying, but I still took some photos of it.  I wasn’t exactly sure what it was, so when I got home, I Googled “beetle with hairy chest” – Hah! – and the correct identification actually came right up.  It was, of course, a “June Bug” or more correctly a May Beetle, Phyllophaga sp.  Around that same area, I found the shed skin of a snake, including its face.

June Bug, May Beetle, Phyllophaga sp.,

I could hear Red-Shouldered Hawks yelling at each other across the forest while I was out there, and at one point a fledgling flew down out of a tree onto the ground beside the trail.  I couldn’t tell if he actually caught anything or if he was just practicing, but he sat for a moment and looked over his shoulder at me so I could snap a photo before he flew off again.

Just as I was leaving, I came across the nesting cavity of some Tree Swallows. I watched them take turn flying in and out of the cavity a few times and got some photos before heading back to the house.

Checking Out the Spider’s Den and Other Stuff, 05-18-19

I got up a little before 6 o’clock this morning and headed out to the Effie Yeaw Nature Preserve for a walk by myself.  I was trying to beat the rain – and was also on the lookout for slime molds.  I did beat the rain (it didn’t show up until around 3:00 pm), but I zeroed out on the slime molds. I think they need one more sunny day between the rainstorms to wake up.

It was nice and quiet on my walk, although I did come across a few other people. I was able to identify some birds to a couple who I think was visiting the place for the first time, and also directed a photographer to some good spots for photo opportunities. Doing my trail-walker thing.

CLICK HERE for the album of photos.

I saw a lot of the usual suspects: deer, turkeys, Starlings, House Wrens. I saw several bucks in their velvet, including the one with wonky antlers (one long and one short) and a torn ear. He should be easy to recognize from here on out.  And I also saw a doe with one ear that seemed really droopy. I don’t know what might have been bothering that ear; It didn’t look damaged or infected, at least as far I could tell.

A nice find was a male California Quail and one of his brides. I hear the quail at the preserve all the time, but they’re very fast and secretive, so I hardly ever get to actually see them.  This pair were pretty far away from me, across a meadow, but I was still able to get some shots. At one point, the male jumped up on a pile of brush so I could see him. They crack me up; their chubby little bodies look like light bulbs.

I also got to see quite a few female Common Mergansers going up into the cottonwood tree the Wood Ducks were in the last time. There were maybe three or four of the Mergansers, each flying around the tree and landing on different parts of it, quacking in low voices all the while. I don’t know if they were scouting out a nesting spot or were attracted to something else. I got some interesting-angle shots of them.

I was greeted by a pair of Western Bluebirds on another part of the trail. First the female flew in and then the male. They’re such bright, cheery-looking little birds. I always like seeing them.

And there was a very chubby California Ground Squirrel who popped up from her burrow to look around. I think she was pregnant based on her body mass. Their gestation lasts about a month, and then its another 6 to8 weeks before the babies emerge from the burrows. So, we won’t see them until sometime in July, most likely.

By the pond at the end of the Pond Trail were was some very fresh otter scat, so I’m guessing the otter was around there earlier this morning.  I’ve seen otters in that pond occasionally, but they usually wait until there are more crawdads around… The leeches in that pond might deter them, though.

I’m always curious when I find folded leaves or sealed leaf tents on plants, but I recognized what one was before I opened it when I found it on a mugwort plant. I handled it gingerly, and put it back where I found it afterwards.  Inside was, as I suspected, a mama American Yellow Sac Spider, Cheiracanthium inclusum, and her egg sac.

I was careful about how I opened it and handled it, because theses spider can pack a very painful bite (and are believed to bite more people than any other spider). The bite is said to burn like a wasp’s sting (and for sensitive people it can make them sick). The mother spider seals herself inside her rolled leaf tent with her egg mass, which can have as many as 100 eggs in it (although less is typical). She stays with the mass until the spiderlings hatch. After her babies hatch, she’ll stay with them until they’ve all gone through one molt (usually around 2 weeks).  As I mentioned, I set her and her tent back where I found them. She’ll spin new web to close her tent up again. ((Investigating leaf-rolls can be very interesting and rewarding for a naturalist, but just be careful.  You never know what might be inside of them.))

The young coyote showed up again today, in between two deer who didn’t seem to be aware that it was there.  It’s a very young coyote – gangly and thin, a teenager – but is hunting on its own, which I think is kind of unusual.  It moves too quickly, so I can’t tell if it’s a male or a female, but I did manage to get a few better photos of it today and a video snippet.

I got so preoccupied with my photo-taking that I lost track of time, and didn’t get back to the car until 11:30 am… So, I’d been on my feet for five hours. My ankles were killing me during the drive back to the house.

Mostly Bugs and Birds, 05-08-19

I got up around 6:00 and headed over to the Effie Yeaw Nature Preserve for my weekly volunteer trail-walker thingy.  It was totally overcast and about 53° when I arrived at the preserve, but it was sunny and about 65° when I left. Such a huge change in just a few hours.

I saw a lot of different things on my walk today, but the standouts were the European Starlings and Black Harvester Ants.

CLICK HERE for the album of photos.

The Starlings (Sturnus vulgaris) had a nesting cavity that was perfectly viewable from the trail.  The cranky babies inside (I saw two but there might have been more) were almost fully fledged but still demanding room service from their folks, who diligently brought them beakfuls of insects. At one point, one of the parents apparently got tired of me watching them and taking photos, and it spat the insects onto the ground before glaring at me from the side of the tree. Hah!

And the Black Harvester Ants (Messor pergandei) always fascinate me. They’re always so busy, hard-working and determined. I saw some heaving large seeds around and carrying dead bees and some kind of grubs to their nest. ((The photos and video snippets I got of the ants were taken with my cell phone.))

I walked for about 4 ½ hours. Phew!

Lots of Nesting Birds, 04-30-19

I got up around 5:30 and was out the door by about 6:15 am to go to the Effie Yeaw Nature Preserve for my regular Tuesday trail-walking gig. The weather was beautiful: about 53° when I got to the preserve and about 70° when I left. Sunny and a little bit windy.

I saw LOTS of birds’ nests: European Starlings bringing some twigs for the nesting cavity and some bugs and worms for the hatchlings. (I could hear the babies squawking inside the tree); Phoebes bringing bugs for their babies; an Oak Titmouse carrying fecal sacs out of her nest; a male House Wren showing a nesting cavity to a female, even going to far as to get into the cavity himself, stick his head out and sing to her. Hah!

CLICK HERE for the album of photos.

Saw lots of squirrels, especially young Fox Squirrels who were running around, jumping, and putting just about everything they could into their mouths.  Generally, acting “squirrely”. Hah!

I found some caterpillars I’d never noticed before on the Redbud trees. They were pale green and had folded themselves inside the soft leaves of the tree.  You’ll never guess what they’re called…  Redbud Leaf-folder Moth caterpillars. Sometimes the names are like, “Duh!”, obvious.

I also found caterpillars on the leaves of the blackberry bushes, and these guys were tricky. They had an escape hatch, so if I touched the front of their silk “nest”, they would zip out the back and fall onto the leaf below them. Some of them had black faces and some of them had reddish-tan faces. I haven’t really ID-ed them yet.

And, of course, there were Tussock Moth caterpillars everywhere.  Here’s a video snippet of an active guy on the top of one of the water stanchions at the preserve: https://youtu.be/Bj9nZiy_EmI

I think I’d mentioned before about the fact that I was finding tiny dirt-clod turrets on the trail.  They look like “hoodoos”; y’know like the big stone ones at Bryce Canyon, but on a tiny-tiny scale.  I couldn’t figure out what was making them, so I put my naturalist students on the hunt for information. Naturalist graduate Deborah Dash sent me some photos of the Diadasia bees and the turrets they make, but all of the photos were from the top of the turrets not the side, so I couldn’t really compare them to the photos I had.  But, that tip led me to look up other Diadasia bees, and I think I found the right one.  I now believe these are the turrets of the “aggregate nests” of the solitary, native Mallow-Loving Digger Bee, Diadasia sp., subgenus Coquillettapis, This website shows how the turrets are created. So neat! (http://nathistoc.bio.uci.edu/hymenopt/Diadasia%20Coquillettapis.htm)

Near the end of my walk, I couldn’t understand why I was so frigging tired. Then I looked at the time and realized I’d been walking for FIVE HOURS!  Yikes!  I get so wrapped up in what I’m seeing on the trail that I lose track of time.
