I've seen flying foxes narrowly escape the clutches of raptors, while still
managing to fly to safety
with huge rents in their wing membranes. I suspect the dynamic many-jointed
wings of bats can
partially compensate for compromised membranes. Pterosaurs probably didn't have
adaptable a wing as bats do - although perhaps the reinforcing actinofibrils
helped to prevent rents
to begin with.
I've heard that small injuries to the flight membranes of bats will eventually
heal and close up,
although I've seen many flying foxes with membranes that have healed to form a
hole in the wing.
As long as the hole isn't too large, it doesn't seem to affect their flight
capabilities in any
