On Tuesday we were working on the western shore of Ibsley Water again with the volunteers. Over the years we have been controlling ragwort and nettle that used to be the dominant here to convert it to grassland, at last we are seeing some real results. Much of it is now mainly grass with a good range of herb species, especially bird’s-foot trefoil. We are also seeing a lot more butterflies and other insects, marbled white are especially frequent in the grass there now.
As we worked I heard a lot of Roesel’s bush-cricket and saw field grasshopper and meadow grasshopper. The grassy sward is not ideal for all species though, the mottled grasshopper likes grassland with lots of bare ground and very dry conditions, at Blashford they are mostly found on the lichen heath.
One distinctive thing about the males of this species is that the ends of the antennae are bent out and swollen, they are also our smallest grasshopper. The males were chirruping, or more correctly stridulating, the object of this is to attract a female and I found one that was evidently playing the right song.
The females are quite a bit larger and have more conventional grasshopper antennae.
