San Dimas Canyon Creek - Microhabitat
« on: June 19, 2016, 11:39:19 pm »

Despite how hot it's been in drought-ridden So CA, there is still a little bit of water left in San Dimas Canyon Creek:

The Terrain

Many insects and reptiles are "getting what they can" out of the last water that remains here, and today tells a fun little pictorial as to what I encountered there in the hour or so I was able to stand the heat (110°).

The filtered light was also a continual challenge, with extremely-bright (and extremely-dark) smatterings throughout.

That said, the first critter I came across was a Great Basin Fence Lizard male, who was letting me know who's boss, by his position on top of the rock in the first image above :)

Great Basin Fence Lizard (Sceloporus occidentalis longipes)

Less than 10' away, on the ground, was another male challenging him:

Great Basin Fence Lizard (Sceloporus occidentalis longipes)

I was able to get closer to this male, and then I noticed one more (in the shadows) of which I was only able to capture a single image before he took off:

Great Basin Fence Lizard (Sceloporus occidentalis longipes) *severe crop*

But the real story was in the many treefrog-letts that had recently hatched from tadpoles, trying desperately to "stay close to the moist rocks" :)

Baja California Treefrog (Pseudacris hypochondriaca)

Nikon D810 | Voigtländer 125mm f2.5 APO-Lanthar Macro | ISO 64 | f/11 | 1/6

Baja California Treefrog (Pseudacris hypochondriaca)

This species varies greatly in its coloration and can change color at will ...

Baja California Treefrog (Pseudacris hypochondriaca)

One of the things I did was push my camera to the limits as this 1/0.4 image shows ... as these two were hidden deep in the shadows :)

Baja California Treefrog (Pseudacris hypochondriaca)

Of anecdotal interest, great droves of honeybees were also feasting in the muck, gulping down as much water as they could in this otherwise desolate (again, 110°) climate, while they still have a chance:

Honeybees (Apis mellifera)

Mountain Mahogany Hairstreak (Satyrium tetra) - ID NOT CONFIRMED

I am still waiting confirmation on this Hairstreak from BAMONA, but it's a lifer to me, no matter what it is :)

Nothing fancy about any of these images; just sharing a lil' hike over the weekend.

One image did amaze me though, which was Image #4, the severe crop I was able to get from what looked like a junker image.
