Oh my god yes <| sep |> To elaborate on the comment by uchandalowe , identifying arthropods down to the genus and species taxa can be very difficult . There are often very minute differences that are difficult to discern from even a photograph taken by somebody who knows how to best show these differences . Much more so in a photograph taken in poor lighting with a phone camera by somebody who is afraid of the specimen . So when we say it appears , it is just because we can make our best educated guess based upon the evidence we see , but we cannot be certain of our identification without examining factors such as eye pattern , pedipalp size , and other minute details that people who don ' t have an interest in entomology and arachnology don ' t think about .
