While bees are critical to sustaining a large proportion of global food production, as well as pollinating both wild and cultivated plants, they are decreasing in both numbers and diversity. Our understanding of the factors driving these declines is limited, in part, because we lack sufficient data on the distribution of bee species to predict chan...

The sugarcane borer or corn stalk borer, Diatraea Guilding is polyphagous insect pest of many important crops such as corn, sorghum and sugarcane. Losses arising from the attack of Diatraea species have been a serious problem, which may cause loss in sugarcane production around 0.25% in sugar, 0.20% in alcohol and 0.77% of body weight for every 1%...

The Lepidoptera of North America Network, or LepNet, is a digitization effort recently launched to mobilize biodiversity data from 3 million specimens of butterflies and moths in United States natural history collections (http://www.lep-net.org/). LepNet was initially conceived as a North American effort but the project seeks collaborations with mu...

Six new species of the genus Distatrix Mason from Central and South America, D. loretta, D. xanadon, D. vigilis, D. pitillaensis, D. pandora Grinter, n. sp., and D. antirrheae Whitfield & Grinter, n. sp., are described from large-scale caterpillar inventory endeavors, mostly from the larvae of geometrid moths. Biological information and diagnostic...
