Swampy is third-party python package through pip installed, but flake8 don’t detect it.

Your question made little sense without a great deal of context, so I went off in search of context and found https://github.com/scrooloose/syntastic/issues/1333 and https://github.com/klen/pylama/issues/29 and I understand what you're asking now. In the future, please don't make myself or anyone else go through the trouble of determining your question when you could include all of the details in your first post.
The problem isn't that flake8 (or more accurately, pyflakes) cannot detect swampy, it's that by importing *, pyflakes through purely static analysis will not be able to tell you when you have unused imports because the symbols imported are not in the text. PyFlakes will not introspect anything on your python path to determine symbols used or anything else like that because that could become computationally expensive. If you want PyFlakes to stop issuing this warning, you should do
from swampy.TurtleWorld import thefunction, theotherfunction, ThisClass, ThatOtherClass
Depending on what you need from it. Alternatively, just import the submodule like
from swampy import TurtleWorld
And use qualified references to the functions/classes that are inside it.
There is no bug with flake8 (or pyflakes). At best, the wording could be made easier for developers whose first language is not English. At worst, you should look into the myriad of style guides for Python that tell you not to use wildcard imports (like Google's https://code.google.com/p/soc/wiki/PythonStyleGuide#Python_Language_Rules or PEP8 https://www.python.org/dev/peps/pep-0008/#imports).
