This photo of a monarch butterfly was taken by my daughter today in our garden. While there are quite a few butterflies around we have few caterpillars on our swanplants. At the beginning and end of summer a few caterpillars make it through to adulthood but none for the bulk of the time. It’s the same every year so no surprise but still frustrating. Eggs are laid, caterpillars hatch, wasps eat them. I’m not sure if all four wasp species are to blame (common, German, Asian and Australian) but we often find caterpillar skins emptied of their body juices. Monarchs must be doing well in someones garden though because, as you can see, they are still with us.
