No.  WinPcap doesn't, as far as we know, support the Microsoft Loopback
Adapter, and Ethereal uses WinPcap on Windows (and libpcap, and the
underlying capture mechanisms it uses, on various flavors of UN*X) to do
packet capture.

You might want to ask the WinPcap developers:

    http://winpcap.polito.it/contact.htm

about that.
