Another invader

Someone out in Blipland can probably tell me what it is.
After a couple of hours gardening I sat in the sun (still needing plenty of clothes on) to read my magazine and have a cuppa and this visitor arrived.
The morning was Keepfit, taking someone into town to the bank and doing the shopping.
The evening was at church where we had food and Mr Rat spoke about Ghana and the work we support, there were a good number of visitors.
