This work investigated eight species of Lepidoptera associated with Miconia calvescens DC. (Myrtales: Melastomataceae) in Brazil, including six defoliators, Salbia lotanalis Druce (Lepidoptera: Pyralidae), Druentia inscita Schaus (Mimallonidae), Antiblemma leucocyma Hampson (Noctuidae), three Limacodidae species, a fruit borer Carposina cardinata Meyrick (Carposinidae), and a damager of flowers...

Abstract Thermal adaptation is a key facet safeguarding organismal function among ectothermic organisms. In this era of rapidly changing environments, understanding the diverse mechanisms mediating climate stress resistance have become priority given contrasting effects on organisms, vis declines in keystone species and an increase invasive pest species. Here, we review patterns thermal shiftin...

We investigate four different methods for background estimation in calcium imaging of the insect brain and evaluate their performance on six data sets consisting of data recorded from two sites in two species of moths. The calcium fluorescence decay curve outside the potential response is estimated using either a low-pass filter or constant, linear or polynomial regression, and is subsequently ...

While an extensive literature exists on the negative effects of invasive species, little is known about their facilitative effects on native species, particularly the role of invasives as trophic subsidies to native predators. The invasive gypsy moth (Lymantria dispar) undergoes periodic outbreaks during which it represents a super-abundant food source for predators capable of consuming it, par...

In 2006 the U.S. National Park Service initiated a long term study of the Lepidoptera at White Sands National Monument, Otero County, New Mexico. Schinia pogueisp. n., described here, was discovered in 2007, the second year of the study. The male and female adult moths and genitalia are illustrated.

To examine the community-wide effects of introduced biocontrol agents on Kauai Island, Hawaii, we constructed quantitative food webs showing interactions among plants, moths, and moth parasitoids in a native forest. Eighty-three percent of parasitoids reared from native moths were biological control agents, 14% were accidental immigrants, and 3% were native species. Although parasitism by biolo...

After the wind was stopped in an insect flight tunnel, male oriental fruit moths continued to fly in zigzag fashion along a stationary pheromone plume. Their lateral excursions from the time-averaged pheromone plume were no greater without wind than in wind of 38 centimeters per second. When the pheromone plume was removed and the wind stopped, males initiated wider track reversals when they re...

Caterpillars and moths (order Lepidoptera) are uncommonly recognized causes of adverse cutaneous reactions, such as localized stings, papular dermatitis, and urticarial wheals. These reactions are typically mild and self-limited; however, in South America, the sting of Lonomia caterpillars can cause a potentially fatal hemorrhagic diathesis related to massive fibrinolysis. In addition, ocular i...

The authors present and discuss some aspects of injuries caused by larvae of Lepidoptera (moths), emphasizing the skin manifestations and intense pain that characterize these conditions. Moreover, they present moth larvae that cause extracutaneous manifestations, such as severe coagulation disorders and ankylosing arthropathies, and dermatitis related to adult insects. The main groups of Lepido...
