Histiostoma feroniarum (Dufour)
Natural host.—Pycnoscelus surinamensis, Germany (Roeser, 1940): Though not parasitic, the mites at times became so numerous that the insects were hindered in their movement, were unable to feed, and died. The mites were introduced with soil and leaves and had originally been attached to millipedes, waterfleas, and sowbugs.
The deutonymphs, hypopial forms, or travelers are found on insects; the other stages are found in decaying organic matter (Baker and Wharton, 1952).
