Hello there. Just put this fellow out today, it had a body length of about 8mm. This is the red type we get in our house . Others are all black and larger (some with black legs some with red/brown, some with a white cresent on the front of the abdomen) a further type seems to be quite similar to this one but mid to dark brown. Are they all they all the same ? or do I have different types? Thanks Lewis.
