It's spring, and butterflies are everywhere in the local parks.
If you like butterflies and live in Northern California (or anywhere
with a similar climate), get yourself out this weekend ot check out
There are a few northern checkerspots, tiger swallowtails and others
flitting about, but the real partiers are the variable checkerspots.
At Stevens Creek, they're clustered in huge numbers on the pale
blue-violet flowers of yerba santa. Some yerba santa bushes are
completely covered with butterflies. Others aren't: a closer look
shows that those bushes have flowers pointing down, rather than up.
Maybe once a flower is pollinated and its nectar gone, it sags?
On the other side of the road, at Piccheti Ranch, yerba santa isn't
so common, and the checkerspots gather on the last of the clusters of
more checkerspot-on-yerba-santa picture, just 'cause they're pretty.
