It's dumping rain right now but 20 minutes ago I was outside working and there were 17 Eastern Tigers feeding on my lilacs, all yellow forms. I mention the color because later in day, at least when the sun is shining, the percentage will be about 60% yellow and 40% blacks. This has been happening ever since the lilacs started blooming which was about 2 weeks ago. Another odd thing is that yesterday I was driving around late morning and early afternoon and I saw many ETSW's but not a single black one flying about.
