Of the 13 monarchs I released in July, one pair stayed in my yard until the next day and mated on the liatris. What a thrill to witness. They stayed together from at least 2:30 pm (when I first noticed them) until I last checked at 10:30 pm. They were gone the following morning. I was amazed that they flew around somewhat on the liatris and also nectared while together like this. I know it's not unusual for butterflies/moths to mate with other butterflies/moths from the same parent, but will the eggs she lays make healthy new cats/adults?
