A rainy day Caterpillar (Lepidoptera sp.), photographed near the junction of the Rim and Stevens Creek Tony Look Trails at Stevens Creek County Park in western Santa Clara County, CA. This is obviously the larvae of a butterfly or moth in the family Lepidoptera. However, I am not very good at getting to species with caterpillars, so I am leaving that exercise to those members of the iNaturalist community who are dedicated caterpillarophiles....

A Western Gray Squirrel (Sciurus griseus), photographed near the intersection of the Coyote and Hill Trails at Rancho San Antonio Preserve in western Santa Clara County, CA. Note the huge, grayish, silvery-edge tail with no brown in it, the more silvery tone to its fur coat when compared with the Eastern Gray Squirrel (Sciurus carolinensis), and the lack of any brown tones whatsoever in its face. Evidently, this squirrel was buildng a nest at the time that this photograph was taken (early March).

A Cluster Fly (Pollenia sp.), photographed on private property in Sunnyvale, CA. I identified this insect as being a Cluster Fly based on the following observed characteristics: (1) the three-segmented antennae located between the eyes, with each antenna bearing a plumose (feathery) appendage known as an arista; (2) the single pair of wings; (3) each wing having a brownish membrane at the base known as a calypter, which conceals the fly's halters; (4) the sharp bend to the "M" vein near the apex of each wing; (5) the long, crinkly golden hairs evident on the fly's thorax; and (6) the non-metallic black-and-silver pattern to this fly's abdomen.

Note: These characteristics seem to strongly suggest that this insect is a Cluster Fly in the genus Pollenia; however, as I am no entomologist, it is entirely possible that I have gotten this identification wrong. Suggestions and corrections are welcome!

The nymph of a Mediterranean Katydid (Phaneroptera nana), photographed on private property in Sunnyvale, CA. Identification was based on visual similarity to other nymphs confirmed as being P. nana online (see, for example, the pictures at the following links on Bug Guide: https://bugguide.net/node/view/1055428 and https://bugguide.net/node/view/1382799). I also have seen adult Mediteranean Katydids in the area where I found this nymph, and it makes sense that they would be reproducing there.

Note: The nymphs of Scudderia sp. are very similar, but according to Bug Guide (https://bugguide.net/node/view/38733), Scudderia sp. nymphs have fewer white rings in their antennae than the nymphs of P. nana. The nymph in my photograph appears to have many white rings in its antennae.

A mature Valley Oak (Quercus lobata), photographed near the southernmost tip of Grant Lake at Joseph D. Grant County Park in Santa Clara County, CA. Note that there are six photograps in the set of pictures documenting this specimen:

Shot 1: Shows the entirety of the tree from its east.
Shot 2: Shows the entirety of the tree from its north.
Shot 3: Provides a view looking up into the tree's canopy.
Shot 4: Gives a moderately close-up view of the tree's bark.
Shot 5: Provides a moderately close-up view of a cluster of the tree's leaves.
Shot 6: Provides a extreme close-up view of one of the tree's leaves.

Observe the following:
1) The tall and relatively gnarled stature of the tree.
2) The tree's relatively open canpy.
3) The rugged, pale gray bark.
4) The irregularly lobed leaves that are oblanceolate to obovate in outline, with the sinuses between lobes reaching less than halfway to the leaf's midrib.

This tree was approximately at least 100 feet tall, with the girth of its trunk near the base being between 4 and 5 feet (1.5 to 2 meters) in diameter. The leaves were fairly variable in size, with the single leaf shown in Shot 6 being around 7cm long, from the base of the leaf to its most distal lobe.

A Long-jawed Orb-Weaver Spider (Tetragnathidae sp.), photographed at night on private property in Sunnyvale, CA. I have included 3 photographs in the set of pictures documenting this specimen:

Shot 1, which provides a close-up, ventral view of the spider;
Shot 2, which provides a close-up profile view of the spider; and
Shot 3, which provides a broader view of the spider as it sitting at the center of its web, which is obvious an orb web.

Note: I think this individual might belong to one of the species in the genus Tetragnathida, but I need to study it more to see if I can really make that conclusion. I'll be coming back to this one later.....
