A rearing of Harrisinopsis robusta Jordan, 1913 (Zygaenidae: Procridinae) in Suriname is described. A cluster of 30–40 last instar, aposematically colored, larvae was found feeding on Hirtella paniculata (Chrysobalanaceae). Three females eclosed in April 2019 and two males in April-May 2020. The phylogeny of the Monalita-Harrisinopsis species group is shown, the habitus and genitalia of the species figured and the genus Monalita Tremewan, 1973 is synonymized with Harrisinopsis Jordan, 1913. Both sexes of H. robusta are described as are the last instar larvae and cocoon. The biology of the species is discussed.

Stiria comprises a group of 14 North American noctuid species that has radiated across the desert and dryland communities of Mexico and the southwestern United States. Stiria caterpillars are hostplant specialists, generally feeding on the flowers and seeds of a single or closely related species within the Asteraceae tribe Heliantheae. Their larvae exemplify the power of natural selection to shape and mold larval phenotypes across instars to match the developmental changes of their host flowers. We infer a preliminary molecular phylogeny for Stiria, describe Stiria brava sp. nov. from West Texas, and report six new larval hostplant associations for the genus. Identity of S. brava can reliably be determined by external adult morphology and COI haplotypes—but neither male or female genitalia provide definitive diagnostic features (across the genus). Larvae of S. brava are specialists on Jefea brevifolia. The adult, male and female genitalia, and larval stages are described and illustrated.

Stiria consiste de 14 especies en Norteamerica, y es más diverso en México y el suroeste de Los Estados Unidos. Las orugas de Stiria son especializadas con respeto a las plantas que comen, en general cada especie de Siria comiendo las flores y las semillas de solo una especie, o especies cercanamentes relacionadas, de planta en el tribu Heliantheae de Asteraceae. Sus larvas ejemplifican el poder de selección natural de formar y moldear fenotipos larvarios a través de los instares tal que los cambios en la aparencia de las larvas se emparejan a los cambios en aparencia que ocurren en las flores hospedantes en las cual se alimentan. Inferimos una filogenia molecular preliminar para Stiria, describimos Stiria brava sp. nov. del oeste de Texas, y reportamos seis historias de vida nuevas para el género. La identidad de S. brava puede ser determinada con certeza por morfología externa de los adultos y haplotipos COI—pero ni la genitalia de los machos ni las hembras proveen características de diagnóstico definitivas (para ninguna especie dentro del género). Larvas de S. brava son especialistas en Jefea brevifolia. El adulto, genitalia masculino y feminina, y las etapas larvarias son descritos y ilustrados.

Butterfly assemblages were studied from 2004 to 2007 at sites along the San Diego River. The purpose was to provide baseline information in the face of possible river improvement projects. We sampled in a protected area and in urban environments in hopes of identifying butterfly assemblages associated with a variety of riparian types. Multivariate analysis identified environmental variables significantly associated with butterfly assemblages such as riparian rank, soil moisture, air temperature, wind speed, nectar abundance, and forb & graminoid richness. There were significant correlations between butterfly species richness, butterfly abundance and a variety of environmental variables, including % shade. Sites located in the Mission Trails Regional Park contained unique butterfly species and were considered high value reference sites. Some butterflies of conservation interest were encountered such as: Panoquina errans Skinner, 1892 (Hesperiidae), Zerene eurydice Boisduval, 1855 (Pieridae), Tharsalea hermes W.H. Edwards, 1870 (Lycaenidae), and Apodemia virgulti Behr, 1865 (Riodinidae). A butterfly-centric metric was derived using species richness and significant variables identified via multivariate analysis to aid in management/monitoring of San Diego riparian sites.

Pistachio fruit hull borer, Arimania komaroffi (Rogonot) (Lepidoptera: Pyralidae), is a damaging insect pest of pistachio (Pistacia vera L.) cultivars in Iran and some other areas of the world. In this research, A. komaroffi was reared on the fruit hull of different commercial pistachio cultivars (Ahmad Aaghaei, Akbari, Kaleghochi, Momtaz and Ohadi) at 25±2°C, 45±5% R.H. and a photoperiod of 16:8 (L: D) h, and its life history and life table parameters were investigated. To evaluate the development, survival and body weight of pre-adult stages, sixty first instar larvae were reared on the fruit hull of each pistachio cultivar. Also, the weight of shelters made by larvae was measured on each cultivar. After emergence of adults, fecundity (number of eggs deposited), incubation period, and adult longevity were recorded. Based on the obtained results, cultivar Ohadi was unsuitable for population increase of A. komaroffi, because a prolonged immature period and the lowest values of food consumption (FC), larval weight gained (LW), shelter weight (SW), and population growth of the pest were on this cultivar. However, cultivar Momtaz was relatively suitable for this pest, since the shortest immature period, and the highest FC, LW, SW, and population growth were on this cultivar. There were significant positive correlations between SW of larvae and FC, LW and intrinsic rate of increase (r_m). Our results showed that Ohadi was relatively resistant, and Momtaz was relatively susceptible cultivars to A. komaroffi development and population increase.

The genus Rinaca Walker 1855 was established with the type species Caligula simla (Westwood 1847) from Simlah (=Shimla), India. Rinaca lindia (Moore 1865) was first reported from northeast, India. During the present study, two specimens of Rinaca lindia (Moore 1865) were collected from the Babareshi region of Jammu and Kashmir (J&K), India, after a 38-year absence. The current study reports the rediscovery of Rinaca lindia (Moore 1865) J&K, India, with description of novel morphological characters and, illustration of the female genitalia. Additionally, information on the preimaginal instars, food plants and species distribution are also provided.
