In May 2007, Rita Carratello & I decided to go look for Exclamation Damsel in Monterey County (as its range in the literature went south to adjacent Santa Cruz Co.), and chose the Monterey County end of the old Walker Street bridge. ... and we found a population there! There are other subsequent records in this vicinity, but this was the first. It is archived & vetted in Odonata Central at OC#7664.

Legs distinctly bicolored, fore-tibia ringed white, abd 1 white, at least one tergite behind abd 1 entirely or partially white, abd 1 & 2 and abd 4 & 5 differ in coloration; scutellar bristles not spine-like, fore-tibia with apical black band stronger than basal band, abd 1 & 4 entirely white, white color extending over anterior fourth of abd 2 & 5, 1A extending far beyond fCu, wings with red-purple-blue reflections. Boesel, 1983.

Giant Wakerobin (Trillium chloropetalum) A.k.a. Giant Trillium or Common Trillium. California endemic plant. It is a native, glabrous, perennial monocot in the Bunchflowers (Melanthiaceae) family that grows 2--7 dm (up to 28 inches) tall. It grows in semi-shaded, moist woodlands, edges of redwood forest, chaparral, and on canyon banks in alluvial soils. 3 Leaves are large, sessile, 7--21 cm long and 7--18 cm wide, rounded to obtuse at tip, generally weakly +- brown-green-spotted or mottled, and whorled around the stout stem. The 3 leaves are located just below the single, 3-petaled flower. Flower colors can be yellow to pink to dark purple, occasionally white. Peak bloom time: April- May.

E. cicutarium, botrys and brachycarpum are all present on this section of the trail, offering ample comparison. (E. moschatum is far away, one day I'll get all 4 together!). E. cicutarium at top, E. brachycarpum at right, and E. botrys at bottom.

I took this opportunity to study these 3 species, most importantly botrys and brachycarpum, the differences of which are poorly documented. I observed 160 E. brachycarpum, and 242 E. botrys.

This observation is for whatever is causing the deformed leaves on this Alliaria petiolata (prev obs).
I saw a number of Alliaria petiolata with these types of deformed leaves. They were in different places, most of which aren't likely to be sprayed with any kinds of pesticides. I looked pretty carefully, and none of them had any aphids or other apparent causative agents.
(tag: mystery alliaria leaf curl)

Spotted nearby an observation of Fritillaria biflora (see Calflora), though it appears the owner of the property mowed it down. Hopefully the bulb survived.
You can see some faint mottling on the dried tepals, which is why I'm calling this affinis and not biflora.
There were three individuals in this spot. I've obscured the exact location.
