Fossil flea in amber. Close-up of a fossilized flea (order Siphonaptera) preserved in amber. Fleas are small, blood-sucking, wingless insects that parasitize a variety of animals including humans. Amber is a sticky resin produced by wounded pine trees, which sometimes traps and preserves insects as it solidifies. This is one of the few processes by which fossils are preserved in a complete form with their soft tissues intact.
