Hi Brian, I thought Roesel's bush crickets were quite rare but I have been reading up on them recently and I noticed they have extended their range. I have just found one in Gillingham Kent. I have never come across one in this area before. Have you any more info on this? Taryn
The collonisation here has been rapid and comprehensive. They were singing from just about any suitable habitat today. I should imagine they are pretty widespread in Kent.
Thanks Brian, I remembered trying to find some for an entomology course I was taking in the early 90's and I never found any. My boss at the time said they were quite rare in this area which was why I was so surprised to find one in my garden. I also noticed her wings are larger than all of the specimen photos that I have found on the internet so I was wondering if this specimen might represent a subspecies. Taryn
Long-winged (macropterous) forms occur from time to time within the population, especially in warmer years. This is an adaptation which enables the population to extend its distribution during favourable conditions - one of the reasons the species has been so successful in colonising new areas in recent years.
Just been looking up a grasshopper/cricket I found in my kitchen!!! yes in the sink. Interested by the saddle like green edged collar, the large thorn on its tail and huge wings - looks like a Roesel Bush Cricket (F)? Will show pic i took to Biodirversity officer i work with at LVRPA. I am in Enfield North London. Sandra
