[21st July]
I had another harvest of eggs today:
That’s an awful lot of potential caterpillars 🙁 I assume they must have been from two different butterflies as one group looks rather scruffy and the other is very neat and tidy.
It led me to realise however that I have no knowledge of butterfly reproductive habits. Do they mate once and lay a load of eggs (possibly across several plants) and then fly off into the sunset and that’s it? Or can they mate multiple times and lay batches of eggs each time?
And how did I reach the age of mumblety-three without knowing this?
