Each of the last 3 years the number of monarch caterpillars I've seen has been less than half of the previous year. There have been virtually no monarchs this year. In talking with a worker at the nature center she said their butterfly numbers were way down, also. I didn't know that monarchs need specific milkweed - not just any milkweed - and there's been very little growing anywhere this year. Mine did not do real well and I gather others had the same problem.
