Nettle feed

Its that time of year when gardeners start making liquid feed from nettles. Unfortunately its also the time when our most beautifull insects, red admiral. tortoise shell, peacock, coma, painted lady butterflies, ladybirds, lacewings and loads of others lay their eggs on the stinging nettles for theyre larvae to eat.It is possibly the most important food plant in the UK. There has been a severe decline in most of the aforementioned insects.
There is however a simple solution. Please only take nettles from a shadded area as insects require warmth from the sun and wont lay eggs in the shade.
If you can spare the room ,place a large tub of stingers in a sunny spot and watch the fun at close quarters. Thanks.
