A note from Dr. John Carlson, who wrote much of this chapter: "If you have images of skin reactions linked to particular species, I would like to see them. Send images to: Please contact me prior to sending actual specimens by mail. I will generally only provide medical opinions to physicians."

p. 134 An instantaneously painful skin lesion we failed to mention is the bite of a green lacewing larva. Some people have experienced fairly dramatic reactions to these--see, for example, the discussion here.
p. 145 For more images of the larvae pulled from this turtle, and the pupa/fly reared on leftover turkey, click here.
