Management Guide for
Red Turpentine Beetle
The red turpentine beetle (RTB)
is the largest (1/4 – 3/8th inch long)
and most widely distributed bark
beetle in North America. It is a
common pest of forest, shade, and
park trees 8 inches or larger in
diameter. It has been recorded from
at least 40 species of domestic and
foreign conifers, but is most
commonly found on ponderosa,
Monterey, and Coulter pines. It is
not considered to be a tree killer, but
its attacks may indicate that the tree
is stressed and at increased risk of
dying. There is evidence that red
turpentine beetle can kill Monterey
California Gall Wasp
Caching of fungi in tree by Douglas' squirrel. This was a single tree with parts of mushrooms stored on several branches in the same tree. There is also visible feeding sign of a Pacific sideband snail in the algae on the branches.
From Bug Guide
Larvae make linear-blotch mines in oak leaves. When females feed on opening leaves by piercing with their ovipositors and then drinking the juices, the punctures widen as the leaf expands and the full-grown leaf is riddled with holes.
