Immature stages and phenology of Catorhintha apicalis scrutator (Hemiptera: Heteroptera: Coreidae) in Michoacan, Mexico. Very little is known about the biology of Catorhintha species, for which a total of 32 species are known, with 10 species present in Mexico. The aim of this work was to describe the immature stages of Catorhintha apicalis scrutator. For this, adults and nymphs were collected as part of a project to study the Hemiptera diversity in contrasting environments in the Cuitzeo Basin, Michoacan. Sampling was done by direct collections and entomological nets; and a total of 523 individuals, 452 nymphs and 71 adults were collected during one year. The 84% of individuals were collected during the rainy season with the greater abundance in August and September, when Mirabilis jalapa (Nyctaginaceae) its host plant, was also more abundant in the study area. All instars were described and notes about their biology and phenology are provided, including the association with its host plant Mirabilis jalapa; besides, comparisons with other species in the genus Catorhintha were made.

Immature stages of Amnestus rugosus (Hemiptera: Cydnidae). In Mexico there are 29 species of Amnestus, of which six species are from Veracruz. The morphological features and illustrations of immature stages of A. rugosus are presented. Notes about the biology and behavior were included. The nymphal and adult stages of A. rugosus were found in remnants of riparian vegetation of the mesophilous forest in La Antigua river basin, Veracruz, Mexico. Twelve sites in five localities were selected and the specimens were sampled in rainy (July) and dry (April) seasons of 2012. The samples were processed in Berlese-Tullgren funnel and Winkler. A total of 419 individuals, 320 adults and 99 nymphs of A. rugosus were revised. The size and coloration of the body and punctuation patterns the immature stages of A. rugosus, A. ficus, and A. morelensis are the main differences among these species. A. rugosus is a first record from Veracruz. Rev. Biol. Trop. 65 (1): 31-39. Epub 2017 March 01.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
