This looks like a native but was growing in someone's yard. Note the fruiting bodies in the second picture.
Most likely a cynipid wasp.
Found this in the backyard of a suburban home. Large in size, looked like a dead leaf. Can anybody tell me what kind of moth it is and if it is in any way harmful (to pets or plants)? There is an apple tree that sometimes gets codling moths, but it does not look like a codling moth. Will this moth harm the apples?
Juvenile (with parent)
Lots of Blue Oaks. We're hoping to join a study looking at the effects of drought on these trees. So we spent this morning identifying all the trees along this ridge. Many Blue Oaks, some Oregon, many Live Oak (mostly agrifolia but I think maybe one canyon).
Recent fall. Wasn't here last week. Broken at the base showing some root rot. This tree was huge, and two of the other trunks had already been previously cut probably to accomodate the power lines overhead. This one tumbled into the trail. The broken branch on the trail had a large twig and mud (possibly crow?) nest inside. The weirdest part was finding twisted acorns on the tree. Is this normal? See the last two photos in the series.
Cone-shaped gall on underside of blue oak leaf. Striped like a peppermint candy. Top of the cone flexible and soft to the touch. Otherwise firm but can be popped off the leaf with a fingernail
This guy has been eating my tomatoes and tripped the rat trap.
Small fly, less than 10mm.
Extensive stands of this where the drying marsh has receded.
Never seemed to land; this is the best I could get.
This must have be planted but they seem to have gone wild.
This pine tree was killed by this fungus or the fungus invaded it after it died.
These guys are enough to make me believe in spontaneous generation.
One tree seemed overloaded with these galls, especially on certain leaves that were nearly covered. Other examples were on brown, fallen leaves on the ground.
