warbles
A defect in leather seen as small pinholes or as
tiny scars. Warbles are caused by the larvae of
the grub or warble fly (family Oestridae), which
develop under the skin of the animal and emerge in
the area of the backbone. If the animal is
slaughtered before the wounds heal, the defect is
known as "open warbles," while if sufficient time
elapses for the animal to develop scar tissue,
they are then called closed or "blind warbles." In
either case leather produced from a warbled hide
is unsatisfactory in both strength and appearance.
