Discussion: Chortoglyphus arcuatus (Troupeau) has been recorded

 barn and from an old stable in England, from stables and hay in Italy, 

 as well as on rabbit excrement, on flour in France, in debris in freight- 

 ers, and in a poultry house in Massachusetts. Fusacarus laminipes 

 Michael has been taken from moles' nests (but not upon the mole) 

 by Michael in England.
