It is my duty to relocate this little clan of stinger flies before the siding crew shows up and smishes them, though that may not happen for another month, or possibly longer, as the siding and roofing crews are being ran ragged with all the repair work to be done around here.

Remember....'Vespa' is Italian for 'Wasp'.
