Eublemma amabilis Moore [1884] (Erebidae) and Syncola pulverea (Meyrick, 1907) (Blastobasidae) are the dominant predators of cultured lac, Kerria lacca (Hemiptera: Kerridae), in northern Thailand. Two additional gelechioid species, Scythropiodes lacca Adamski, n. sp. (Depressariidae: Oditinae), and Stathmopoda venustaMeyrick, 1913 (Stathmopodidae) are, to a lesser degree, also predatory on lac insects. Several species of detritivorous Lepidoptera are found on lac-infested branches of Samanea saman (Jacq.) Merr. (Fabaceae) including: Erechthias leucopogon (Meyrick, 1924) (Tineidae), Stenachroia elongellaHampson, 1898 (Pyralidae: Galleriinae), Cryptoblades gnidiella (Millière, 1867) (Pyralidae: Phycitinae), and Pyroderces spatulata Adamski, n. sp. (Cosmopterigidae). Adults of all species associated with lac are described or redescribed. Detailed descriptions of available immature stages of these lac-associated moth species are supplemented with chaetotaxal maps, illustrations, photographs, and scanning electron micrographs. A lectotype is designated for Blastobasis pulvereaMeyrick, 1907.

The butterfly assemblage at Roxborough State Park, Douglas County, Colorado was examined for long-term and short-term changes over 41 years. Seven surveys occurred between 1979–1995 (=historic) with more recent surveys in 2018 and 2019. We compared flight phenology and species assemblages between these periods. Increased monthly species richness in 2018-2019 may have been related to decreased grazing and/or climate change. Additional species were noted in 2018 and 2019, however, some species from 1979 to 1995 went undetected. In most cases, species detected on a very common (VC) basis (calculated from interquartile ranges) between 1979 and 1995 were still VC in 2018–2019. Long-term temperature data (1979-2019) indicated a significant increase over time in winter temperatures. VC species mostly had earlier dates of first flight (DFF) in 2018 compared to historic. However, 2019 DFF's were later. Temperatures differed significantly between 2018 and 2019, with lower winter and spring temperatures in 2019. Eight species were newly detected in 2018-2019. Three of these: Erynnis horatius, Speyeria coronis, and Polites themistocles, were found in both years suggesting they are persistent members of the Roxborough assemblage. Including historical surveys, the Roxborough species list stands at 102. Perhaps surprisingly during times that suggest a decline of insects, including butterflies, Roxborough State Park has shown a degree of resiliency. We will suggest reasons for this apparent persistence.

In the present article, the biology, external morphology of the immature stages and variation in adult phenotypes of the butterfly Orophila campaspe (Hewitson) are described. The food plant is Weinmannia tomentosa L.f. (Cunoniaceae). Larvae were observed and collected in the Eastern Cordillera, north of Bogotá, Colombia and reared in the laboratory. The results are discussed and comparisons made with other species of the subtribe Callicorina.

Lepidoptera at a single mid-elevation site in the central Cascade Range in Washington state were surveyed for six full seasons spanning 11 years (2009–2011, 2017–2019). Sampling was performed continuously with a blacklight trap, and was supplemented with pheromone traps, searches for immature stages, day collecting, observation, photography, and sugar bait traps. The habitat is forested transition zone, including old growth forest, slightly east of the Cascade divide in the southern part of the North Cascades ecoregion. The fauna of 822 species is categorized by the number of seasons each species was found over the span of the study. The higher-order distribution of the fauna within Lepidoptera, impact of sampling methods, annual and multi-year fluctuations in abundance, and local climate effects on flight period are presented. Taxonomic challenges and noteworthy records are discussed. Representative species and genitalia are illustrated.
