I have not heard a grasshopper either, but not really thought about them. There are wild flowers around here (still Lincolnshire - the Snowdrops were brilliant earlier in the year) and there are lots of different types of butterflies around (this may be due to me looking more closely to find different ones lol). My greenhouse seems to be filled with Hoverflies this year, and I have seen a few different species of Hornet / wasp. Bumble bees, as well as Honey seem to be doing well, but my garden is like a wildlife sanctury as I grow lots of different things. Interestingly less Ladybirds than usual.
