A pointer for those who live near Boise, Idaho.  As you drive up Bogus Basin Highway, and other highways north and east of Boise, sometimes you will find isolated willow trees growing along the side of the road or growing here and there in ravines between 3500 and 5000 feet.  Sometimes it is not difficult to find lorquin's admiral eggs and caterpillars between April and September, or hibernacula during the winter months.  For everyone else, it is always advisable to look for butterfly eggs and caterpillars on isolated host plants.  Click here to watch a video.
