Decorated granite moth

Found this little decorated granite moth in the bathroom yesterday morning, very similar to the one I posted a few years ago.  I couldn't quite tell if the coloring of this one is more brown than the other, because there is very little natural light in this bathroom and the bulb makes everything a bit golden.

Unidentified birds' nests, possibly northern mockingbird?

These nests were built in our large "Duchesse de Brabant" rosebush this past summer.  I knew of one nest, since when I was out working in the garden one day, the alarmed parents worked their "distraction" techniques on me, hopping a few feet away from the rose bush, chirping loudly, hopping away a few feet more, then chirping again.  Later I could see the nest among the canes near the top of the rosebush, which is about six feet high.  I rarely saw any other activity near the nest, though.

A few weeks ago when we were pruning back the plumbago that had thoroughly infiltrated the rosebush, not one but two nests were knocked out.  There was no evidence of eggshells anywhere, and the nests were both full of rose and plumbago litter, so I don't know if either was used at all, or if the clutch had grown up and left the nest already, or even if one of the nests was last year's.

The nests are about 6" in diameter and about 3" deep (16cm x 8cm), and rather scruffy-looking, though in the builders' defense, pine needles are probably just a little too stiff for tidy construction.  The nests are certainly sturdy, as they survived getting thrashed around and knocked out of the rosebush and have been sitting exposed on the deck for a few weeks now.

Maybe a song sparrow or house finch, by the looks of the nests?  Selecting the appropriate criteria at NestWatch retrieves only lesser goldfinch and northern mockingbird, and I'm pretty sure I have never seen goldfinches here, whereas the mockingbird could be the pair I saw, and we certainly have these night-singers in abundance.

Praying mantis

I saw this mantis as I was sweeping the driveway this morning -- thought it was a stick my broom had missed and was about to pick it up when it started to walk away!  It was very sluggish and crawled up the leg of this pot instead of flying, but it is a cool and overcast morning, so perhaps the mantis just hasn't warmed up yet.

The mantis is generally a beneficial insect, eating flies, mosquitoes, crickets, aphids, etc., but being a voracious carnivore it will also eat other beneficial insects, including other mantises.

Brown marmorated stink bug

We caught this in the house this afternoon -- identified it as a brown marmorated stink bug (Halyomorpha halys). Yuck.

Apparently this bug, accidentally imported from Asia in the 1990s, is now a serious pest, with a website with some pretty big names attached to it dedicated to controlling it. More advice from Penn State is found here.  The bugs feed on soft-skinned fruits such as apples, peaches, grapes, etc. disfiguring the crops and making them unsellable, and the stinky secretion they produce when threatened can cause allergic reactions in humans.

False parasol mushroom

The false parasol (Chlorophyllum molybdites) is a very common and very toxic mushroom, often found in Southern California lawns.  Because its appearance is similar to the edible parasol mushroom, and because it is so often found in lawns, it is one of the most commonly-consumed poisonous mushrooms in North America. Apparently it will not kill you if eaten, but will make you very uncomfortably sick, with vomiting and diarrhea, so is best avoided altogether.

Interestingly, when I picked the mushroom, it looked like this,

and by the next morning the cap had opened and spread to this,

The brown scales had also begun to flake off -- it often looks like this while growing.

The ruler I used was not the best for this lighting, obviously -- this particular mushroom is about 4 inches (10cm) long, but can be found larger or smaller.

A distinctive characteristic of the false parasol is the greenish spores, which are beginning to be apparent in the photo, and came out quite clearly in the spore print I made -- the name "chlorophyllum" comes from the Latin chloro, green, + phyllum, gills.

For further reference, and other pictures to help you identify this toxic mushroom, see the Wikipedia article "Chlorophyllum molybdites", Tom Volk's "Fungus of the month" for August 1999, the C. molybdites pages at California Fungi and Urban Mushrooms.

Bushtit's nest

We noticed this bird's nest in the honeysuckle growing over a chain-link fence in our garden this afternoon.  The nest is about 8 in. long (20cm), and about the size of a grapefruit or large apple at the bottom.  You can clearly see the opening near the top of the nest in the photo above and the next one.

There is an old Bearss lime tree with low-hanging branches above, but the nest is actually in the tangle of honeysuckle, a little less than five feet off the ground.  It is constructed of twigs and leaves and various garden rubbish, including bits of newspaper that we put down as mulch a few months ago, and possibly a piece of pink dryer lint! It is probably a bushtit's nest, but we haven't seen any occupants yet.


The photos are all full-size --

This is the back of the nest, which is on the other side of the chain-link fence.

Tall fescue

I thought this was one of the numerous crabgrasses, but apparently it is tall fescue (Festuca arundinacea). The crabgrass seed heads, as far as I can tell, all have that distinctive splayed-tines formation, while these stay quite close to the stem.  Yes, that's my shovel at the bottom of the photo! it's a weed in our yard.

The seedlings of crabgrass and fescue look remarkably alike.
