I usually raise ~20 caterpillars a year here in the Chicago area, but this year it's a drought. Today I found a full-grown cat on a stray milkweed in front of the picture window and brought it in-doors, since a storm is coming tonight. This is the first egg/cat I saw this year. I have a butterfly garden with 3 species of 20+ milkweeds and counting, but haven't seen any others this year. We do see 2 or 3 monarchs at a time, compared to 7 or 8 previous years.
