On March 18 and 19 along highway 140 in the foothills of the Sierra
Nevada mountains east of the northern San Joaquin valley towns of
Merced and Planada, Calif. I captured 2 minutes of video footage of
monarch eggs on some tiny shoots of Asclepias fascicularis milkweed
growing along a highway turnout

The ground where these shoots had come up had been sprayed with
herbicide a month or two earlier (before the shoots came up) so the
milkweed escaped harm from the spraying.

The likely overwintered female monarch that laid these eggs probably
did so during the stretch of warm weather between March 9 - 18. These
eggs should produce a new generation of adults in 7-8 weeks (May
2 - 18) many of which will migrate north to the Pacific Northwest and
east across the Great Basin. So enthusiasts in northern Oregon,
Washington, Idaho, Utah and Colorado should start seeing monarchs
the first week in June this year.
