Studies of arthropod defensive chemistry continue to bring to light novel structures and
unanticipated biosynthetic capabilities. Insect alkaloids, such as the heptacyclic acetogenin …

It has long been assumed that the North American pipevine swallowtail, Battus philenor
(L.)(Papilionidae, Troidini), is protected from natural enemies by aristolochic acids …

A number of aposematic butterfly and moth species sequester toxic substances from their
host plants. Some of these insects can detect the toxic compounds during food assessment …

As schoolgirls we were riveted by the idea that God's command" Let there be light" was a
terse way of intimating that He had thought up the eye. Later on my own children pushed the …

In reviewing the distribution of micromolecular constituents (secondary compounds) that are
known to function as defensive repellents* in arthropods, it becomes evident that a large …

Carotenoids in 38 species of Lepidoptera have been examined qualitatively and
quantitatively. Comparisons are made between cryptic and aposematic species, pupae and …

We compared the chemical compositions of the osmeterial secretions of fourth and fifth (last)
instars of eight swallowtail species of the tribe Papilionini. Four species (Papilio demoleus …

Insects make up the largest and most diverse group of organisms on earth, contributing to as
much as 80–90% of the world's biodiversity. Approximately 950,000 species of insects have …

The larval osmeterial secretions of six Papilio species examined displayed a remarkable
qualitative change at the fourth larval ecdysis. The secretions of 4th (penultimate) instar …

Many species of the Papilionidae are unpalatable and protected from natural enemies by
aristolochic acids (AAs) sequestered from their Aristolochiaceae food plants. Battus …
