Caterpillar growth spurt

The other day, I admired how lush (beautifully green) my butterfly garden had become. My tall swan plants were all getting quite bushy, some with clusters of delicate white and purple flowers. So I arranged the plants (they are all in pots) and tidied everything, topped up the potting mix, swept up, and watered all the plants. It looked amazing. For a whole day!

Now, suddenly, I have a caterpillar population explosion! Again. This is the third time this summer I have found myself with more caterpillars than I can count. (It is probably the last time, as there are usually three generations of butterflies in a season.)

This is what happened. The other day, I had three or four enormous caterpillars. I admired them, photographed them, chatted to them about how fat they were. As well as those ones, there seemed to be about 20 medium-sized caterpillars, a bunch of little ones, and eggs here and there under leaves and so on. In the space of a few days, my enormous caterpillars gobbled a last meal and found places to pupate (turn into a chrysalis), while the medium-sized ones became fat, and all the little ones got bigger too. Now they’re all more noticeable and easy to see on the plants. And it seems as though they appeared from nowhere!

The other reason they’re more noticeable now is because they have stripped the leaves off several of the smaller plants, so there’s nowhere for them to hide. And they are noticing each other. They seem to eat even faster when there are a lot of them together, probably in case the leaf they’re eating is their last meal!
