Moths and butterflies compose one of the most diverse insect orders, but they are overwhelmingly herbivorous. Less than 0.2% are specialized predators, indicating that lepidopteran feeding habits are highly constrained. We report a Hawaiian caterpillar that specializes on snails, a unique food source requiring an unusual feeding strategy. The caterpillar uses silk to restrain live prey. All caterpillars have silk glands, but none are known to use silk in this spiderlike fashion. Considering the… 

The role of silk threads as lifelines for caterpillars: pattern and significance of lifeline‐climbing behaviour

This data indicates that when caterpillars involuntarily or intentionally drop from the tree canopy, they can regain their original position by climbing silk lifelines spun out from the head spinnerets, but the taxonomic distribution of this climbing behaviour in the Lepidoptera is unknown.

Biology of a New Panamanian Bagworm Moth (Lepidoptera: Psychidae) with Predatory Larvae, and Eggs Individually Wrapped in Setal Cases

The biology and morphology of all stages of a new species of Psychidae from Panama, Perisceptis carnivora Davis (Lepidoptera: Psychidae), are described, andotheses as to how these eggs are wrapped and how the cases may protect the eggs are proposed.

Multiple aquatic invasions by an endemic, terrestrial Hawaiian moth radiation

A molecular phylogeny based on both nuclear and mitochondrial genes representing 216 individuals and 89 species of Hyposmocoma reveals that this amphibious lifestyle is an example of parallel evolution and has arisen from strictly terrestrial clades at least three separate times in the genus starting more than 6 million years ago, before the current high islands existed.

Three new species of Fancy Case caterpillars from threatened forests of Hawaii (Lepidoptera, Cosmopterigidae, Hyposmocoma)

The molecular phylogeny based on mitochondrial and nuclear loci demonstrates that all are distinct species of Hyposmocoma, and the discovery of a new, endemic species from Mt. Tantalus, Oahu suggests that even relatively degraded areas in Hawaii would be worthy of active conservation efforts.

Cannibalism of parasitoid‐attacked conspecifics in a non‐carnivorous caterpillar

The adaptive significance of such cannibalism on parasitoid‐attacked conspecifics with respect to a trans‐generational fitness gain for the population through the killing of the parasitoids, thereby reducing parasitism in subsequent generations is discussed.

Caterpillars use the substrate as their external skeleton

New ground reaction force data from the caterpillar, Manduca sexta suggest an alternate strategy for large soft animals moving in complex three dimensional structures called an "environmental skeleton", which effectively allows the caterpillars to minimize reliance on a hydrostatic skeleton.

Life-history Notes on the Fern-mining Endemic Hyposmocoma (Euperissus) trivitella Swezey 1913 (Lepidoptera: Cosmopterigidae) from Kauai and a Report of Associated Parasitoids (Hymenoptera: Bethylidae)

A large number of Lepidoptera species have been recorded in Hawaii over a short period of time, and the distribution and habits of these species have changed significantly in recent years.

Flightless Hawaiian Hemerobiidae (Neuroptera): Comparative morphology and biology of a brachypterous species, its macropterous relative and intermediate forms*

The natural occurrence of intermediates between this brachypterousMicromus usingeri and its near relative, the macropterous Micromus longispinosus are reported.

Taxonomic revision of the Mecyclothorax beetles (Coleoptera: Carabidae) of Oahu: epithets as epitaphs for an endangered fauna?

These results are consistent with the occurrence of rampant, unfixed infraspecific genitalic variation early in an island radiation, with subsequent fixation of divergent genitalic characters occurring as speciation proceeds.

Development of Insect Conservation in Hawai‘i

As the most isolated group of high islands in the world, the Hawaiian archipelago occupies a very special place in insect conservation: first as a cradle of evolution of a remarkable endemic fauna



Predatory and parasitic Lepidoptera: carnivores living on plants.

This paper summarizes the life histories of the known predatory and parasitic lepidopteran taxa, focusing in detail on current research in the butterfly family Lycaenidae, a group disproportionately rich in aphytophagous feeders and myrmecophilous habits.
