Androlaelaps casalis, formerly known as Haemolaelaps casalis,{{Cite journal|last=M.Sc|first=D. J.

It cannot bite or sting birds and humans because its mandibles are not designed for sucking but for predation on other mites. Because Androlaelaps casalis mites feed off parasitic mites like Dermanyssus gallinae, individuals with red colored abdomens can be found. This is not due to any blood-sucking by A. casalis but is because it has ingested blood-engorged parasitic mites. There is some evidence that it may be associated with dermatitis in humans.{{cite journal |author=S. Rosen, I. Yeruham & Y.
