Wind turned north 20-25 mph and temp began to drop about noon.

At about 1600 I did a quick check for eggs. Found one on 4th plant I checked. As is typical for spring migration, egg was on top of a leaf. A. asperula initially spreads at ground level, so underside is often inaccessible. In addition during rain, the underside is often splashed with dirt, small rocks and plant debris, so not an ideal location anyway.

I didn't find others during a brief check. But not a surprise. In the past ten days A. asperula have gone from one to thousands, rapidly growing from last years roots. The largest have reached nearly two feet in diameter. As usual there is far more milkweed here than Monarchs, so percentage of plants with eggs is always low.
