“Lawmakers are again asserting that the Bush Administration is meddling in science. House Science Committee Democrats charge that federal officials have suppressed a report on potential health threats from pollution in the Great Lakes.

“Young caterpillars of the swallowtail butterfly, Papilio xuthus, are mimics of bird droppings, whereas the fifth larval instar is camouflaged among the leaves of host plants (cryptic pattern). We find that juvenile hormone (JH) titers decrease during the fourth larval instar. Furthermore, treatment with JH analog at the beginning of the fourth instar stage resulted in reproducing the mimetic pattern instead ofthe usual cryptic one and likewise altered gene expression patterns to that associated with the mimetic pattern. “
