Also, very hard to net. They are skittish, too. A naturalist friend has also noticed an abundance of predators. The assassin bugs are out in force and so are the wasp. I have noted an increased presence of Yellow Jackets, too. I finally netted a female and collected around 90 eggs for a three day period. The caterpillars are munching away now.
