It's a kind of magic...

These innocuous looking clusters of yellow eggs can transform themselves into very hungry caterpillars.
And they in turn can transmogrify a verdant grove of kale, into a fluttering cloud of white butterflies.

Back in the late spring, there was a dearth of cabbage whites. As a brassica grower this was a relief, but as someone who enjoys seeing the swallows swooping to catch this usually generous bounty of foodstuff; I was a tad concerned.

The butterflies usually turn up just before the swallows. Just in time for; (or to be) dinner...

Turns out I needn't have worried. The caterpillars and their parents, have been abundant for the past few weeks.
Leaving just enough toothsome greenery, for those humans keen on it too.

The swallows are particularly busy right now. Fattening themselves up for their own remarkable journeys, back down South; mainly to subsaharan Africa for the winter.

Doubtless I'll find some other wildlife related problem to fret about afore long...

Such as fencing the badgers off the fattening cobs of corn...
