It's that time of year again! Look up in your garden on a hot, still evening (just like today's) and you may very well see fat insects silhouetted against the dusky sky, lazily buzzing around the trees. Perhaps bumblebees at first glance, but in fact they're probably chafer beetles. Look down at the lawn at your feet and you might see one that's landed, presumably to lay eggs in the soil.
I've posted about them before, at the same time of year, and this evening as I walked through the garden I thought "it's that sort of muggy summer evening – I bet the chafers are abroad!" And I was right.
What do those eggs turn into? Great big, ugly larvae living under your turf!
