Data for 'Weak latitudinal gradients in insect herbivory for dominant rangeland grasses of North America'
Patterns of insect herbivory may follow predictable geographical gradients, with greater herbivory at low latitudes. However, biogeographic studies of insect herbivory often do not account for multiple abiotic factors (e.g. precipitation, soil nutrients) that could underlie gradients. We tested for
Data from: Coordinated species importation policies are needed to reduce serious invasions globally: the case of alien bumblebees in South America
The global trade of species promotes diverse human activities but also facilitates the introduction of potentially invasive species into new environments. As species ignore national boundaries, unilateral national decisions concerning species trade set the stage for transnational species invasion wi
Oviposition preferences in the sharp-veined white butterfly, <i>Pieris napi</i>
Carcass selection in a high altitude population of the burying beetle, <i>Nicrophorus investigator</i>, (Silphidae)
Predatory and parasitic Lepidoptera: carnivores living on plants
Exploitation of lycaenid-ant mutualisms by braconid parasitoids
Larvae of 17 Lycaenidae butterfly species from Europe, North America, South East Asia and Australia were observed to retain at least some of their adaptations related to myrmecophily even after parasitic braconid larvae have emerged from them. The myrmecophilous glandular organs and vibratory muscle
The Pending Extinction of the Uncompahgre Fritillary Butterfly
Previous mark‐recapture studies and population size estimates indicated that in the 1980s populations of the endangered Uncompahgre fritillary ( Boloria acrocnema ) declined precipitously, apparently leading to extirpation at its type locality. This locality and a nearby second site, both high in th
Uncompahgre Fritillary Butterfly Demographics: Response to Britten et al.
Using the same methods as Britten, my associates and I ran Pollard transects during four flight seasons at Redcloud Peak and during three flight seasons (1991-93) at Mt. Uncompahgre and found that the populations are declining precipitously, genetic analyses show low heterozygosity, and no heroic ef

The effects of pathogen-induced pseudoflowers and buttercups on each other's insect visitation
Pseudoflowers induced by the rust fungus Puccinia monoica on Arabis spp. are flower—like in color, shape, size, nectar production, and scent. Pseudoflowers attract insects that aid the rust's reproduction in a way that is analogous to pollination in flowering plants. I explored the effects of pathog
Categorization of food types enhances foraging performance of bumble bees
Patch dynamics of <i>Glaucopsyche lygdamus</i> (Lycaenidae): correlations between butterfly density and host species diversity
Diapause and the host plant affiliations of lycaenid butterflies
Results of three years of study on the host plant affiliations of two lycaenid butterfly species (Lycaenidae) suggest that differences between the two butterflies in host plant range, plant tissue oviposited on by adults and consumed by larvae, larval growth rates, and adult flight season may be con
