Specimens of Haploembia sp. (Embioptera: Oligotomidae) were found in 2005 in a rural area of the Columbia Basin next to the Snake River. This is the first verified record of Embioptera in Washington State and one of the northernmost in the world. Subsequent collections 16 years later at the same site show that the population is still present. In 2005, specimens were found only at the original locality. However, starting in 2020, specimens of Haploembia were reported in multiple nearby urban and suburban areas of Washington State and Oregon on the citizen science website iNaturalist.org. Characters of collected specimens and a lack of males across 2005 and 2021 suggest the species in the Columbia Basin region is Haploembia cf. tarsalis (Ross).

Records of Coleoptera and their hymenopteran parasitoids are reported from a ten-year study of herbivorous insects of Nantucket, Massachusetts, USA, with a focus on searching for galls, leaf mines, and other characteristic feeding evidence on host plants. Our field observations and reared specimens are compared with Johnson's (1930) list of the insect fauna of Nantucket. We add 25 beetle species to Johnson's list, one of which (Buprestidae: Brachys howdeni Hespenheide) was described using one of our specimens as a paratype. Several new host records are reported, and we provide the first accounts of the larval habits of Erynephala maritima (LeConte) and Oulema palustris (Blatchley) (Chrysomelidae).

Hosts, larval descriptions, biology, and distribution records are reviewed for the 16 described Nearctic species of Caliroa Costa (Tenthredinidae). We report the first rearing records for C. lunata MacGillivray, which feeds on Staphylea trifolia L. (Staphyleaceae). Caliroa obsoleta (Norton), previously known from Quercus L. spp. (Fagaceae), has now been reared from Populus tremuloides Michx. (Salicaceae). The larva of another Quercus feeder, C. petiolata Smith, is described and illustrated for the first time. A key is provided to both known and unidentified larvae, drawing from the literature and new observations, including an extensive review of online photographs.

Archilestris peruvensis new species from Peru is described and illustrated. A key to all the species of the genus and a distribution map are provided.

The terminalia of Fagitana littera Guenée are described with a focus on the complex external copulatory coupling mechanism in the male and female. The female 7^th sternite is robustly developed, enclosing a complex of sclerotized, scobinate structures and pockets, variously fused with elements arising from the sternum and intersegmental membrane of abdominal segments VII and VIII. This scaffold appears to accommodate the robustly developed male clasper, including a modification of the valva's outer margin. Such conspicuous and elaborate external coupling mechanisms are rarely reported in Noctuidae.

The grass-feeding genus Gracilimiris Stonedahl and Henry, 1991 is reviewed and G. rubrolineatus new species, from Arizona and Texas, USA, is described. Provided are a diagnosis, description, and digital images of the adult male and female and male genitalia of G. rubrolineatus; diagnoses, male habitus images, and summary of hosts and distributions of the three previously described species; and a revised key to species to facilitate identification.

Seven new species of the orthotyline mirid genus Hyalochloria Reuter (Hemiptera: Heteroptera) are described: H. dominicae new species and H. wheeleri new species from Dominica; H. decora new species, H. modesta new species, and H. sulcata new species from Ecuador; H. maldonadoi new species from Puerto Rico; and H. trinidadensis new species from Trinidad. Each species is diagnosed and described, and color dorsal habitus images and male antennal structures are illustrated to help distinguish the new species. The identity of “Hyalochloria sp.,” included in Maldonado's (1969) Miridae of Puerto Rico, is clarified and corrections of several errors in the literature are provided.

Calambus jureceki (Stepanov, 1930) is recorded for the first time in China. This species was collected from a coniferous and broad-leaved mixed forest in Qianjin Forest Farm, Jiaohe City, Jilin Province. We provide diagnostic external characters, characters of male aedeagus and female genitalia, distribution and its correlation with forest, and a comparison with congeners known from China. A key to the species of the genus Calambus Thomson, 1859 known from China is given.

Diaochana, a new genus of Cephidae, is established for a new species and three known species originally placed in Caenocephus Konow. A diagnosis of the new genus and the differences between the new genus and Caenocephus are discussed in detail. Dianchana taibaiensis new species is described from Shaanxi, China. The new combinations Diaochana akiyamai (Shinohara, 1999), D. tianmunica (Wei, 1999), and D. xanthopus (Shinohara, 1999) are transferred from Caenocephus. A key to species of Diaochana new genus is provided.

New species records of flower flies (Diptera: Syrphidae: Syrphinae) are reported from China, South Korea, and Malaysia, as well as several new province records for Korea and China. Baccha laphrieformis Violovitsh, Episyrphus perscitus He and Chu, Eupeodes bucculatus (Rondani), Meligramma cingulata (Egger), Parasyrphus punctulatus (Verrall), Sphaerophoria indiana Bigot, and Sphaerophoria macrogaster (Thomson) are recorded from South Korea. Epistrophe aequalis (Walker) is reported from Malaysia, and Epistrophe sasayamana (Matsumura), Meliscaeva strigifrons (de Meijere), and Sphaerophoria reginae Claußen and Mutin are reported from China. The first female specimens of Epistrophe nigritibia Huo, Ren, and Zheng are documented from Zhejiang province, China.

Salmwood (Cordia alliodora (Ruiz and Pav.) Oken) (Boraginaceae) is used as a shade plant for cacao and coffee agroforestry systems in Colombia. In 2016 these trees were severely defoliated by insects on a farm in northeastern Colombia. One hemipteran and one lepidopteran were found to be associated with the damage, and one hymenopteran was found to parasitize the hemipteran. The hemipteran was Edessa panamensis Fernandes von Doesburg and Greve (Pentatomidae), a new record for Colombia and the first record of this species as a parasitoid host. A parasitoid wasp, Neorileya albipes Girault (Eurytomidae), emerged from E. panamensis eggs, and is recorded for the first time from Colombia. The lepidopteran feeding on salmwood was Paridnea squamicosta (Walker) (Pyralidae). The larva takes refuge from natural enemies in domatia on salmwood branches and emerges to feed on leaves. The larval leaf consumption was estimated to be 134.1 cm² with a larval duration of 15.64 days; the pupal stage was 20.44 days. We also report for the first time another host for this larva, the moncoro tree (Cordia gerascanthus L.), which was affected to a lesser degree. Photographs of insect adults, larvae, eggs, and morphological structures are provided.

El nogal cafetero Cordia alliodora (Ruiz y Pav.) Oken (Boraginaceae) es usado como una planta de sombrío en sistemas agroforestales en Colombia, en 2016 estos arboles fueron severamente defoliados por insectos en una finca al noroeste de Colombia. Un hemíptero y un lepidóptero fueron asociados con el daño, además un himenóptero fue encontrado parasitando el hemíptero. El hemíptero fue identificado como el chinche Edessa panamensis Fernandes von Doesburg and Greve (Pentatomidae), un nuevo registro para Colombia. La avispa parasitoide, Neorileya albipes Girault (Eurytomidae), emergió de huevos de E. panamensis y es registrada por primera vez para Colombia. El lepidoptero que se alimenta de hojas de nogal cafetero fue identificado como Paridnea squamicosta (Walker) (Pyralidae). La larva se refugia de sus enemigos naturales en los domacios en las ramas de nogal, desde allí sale a consumir hojas. En la fase de larva el consumo de hojas fue estimado en 134,1 cm² con una duración de 15,64 dias, la duración de la etapa de pupa fue 20,44. También se reporta por primera vez otro hospedero para esta larva, el arbol de moncoro (Cordia gerascanthus L.), el cual es afectado en menor grado. Se presentan fotografías de insectos adultos, larva, huevo y estructura morfológicas.

The predation capacity and prey preferences of Chrysoperla cf. plorabunda (Fitch) on Diaphorina citri Kuwayama, Toxoptera citricida (Kirkaldy); Brevipalpus sp. Baker; and Aleurocanthus woglumi Ashby; economically important pests of citrus, were evaluated under controlled conditions. The study of predation capacity showed that D. citri is the most consumed prey (61.99 ± 4.36), followed by T. citricida (45.23 ± 6.27) and Brevipalpus sp. (24.60 ± 2.82). Chrysoperla cf. plorabunda did not prey on A. woglumi. When combined in the same Petri dish, the Manly's β index indicates a tendency to prefer D. citri over T. citricida and Brevipalpus sp. The results show that C. cf. plorabunda prefers to feed on D. citri over T. citricida, Brevipalpus sp., and A. woglumi.

Se evaluó la capacidad de depredación y la preferencias de presa de Chrysoperla cf. plorabunda (Fitch) sobre Diaphorina citri Kuwayama, Toxoptera citricida (Kirkaldy), Brevipalpus sp. Baker, y Aleurocanthus woglumi Ashby, 1915, plagas económicamente importantes de los cítricos, en condiciones controladas. El estudio de la capacidad de depredación demostró que D. citri es la presa más consumida (61,99 ± 4,36), seguida de T. citricida (45,23 ± 6,27) y Brevipalpus sp. (24,60 ± 2,82). Chrysoperla cf. plorabunda no se alimentó de A. woglumi. Al combinar, en una misma caja Petri las diferentes presas, el índice β de Manly indica una tendencia a preferir D. citri sobre T. citricida y Brevipalpus sp. Los resultados muestran que C. cf. plorabunda prefiere alimentarse de D. citri sobre T. citricida, Brevipalpus sp. y A. woglumi.

Polystoechotes punctata (Fabricius, 1793) (Neuroptera: Ithonidae) was formerly widespread across North America, but was extirpated from eastern North America by the 1950s. We report a specimen collected from Fayetteville, Arkansas, which represents a new state record and the first specimen recorded in eastern North America in over fifty years. We also reexamine a previously published dataset and discuss the history of P. punctata in eastern North America. The importance of community science efforts are discussed and compared with museum holdings. We propose that P. punctata may have always been uncommon in eastern North America, or at least when insect collecting began in earnest in the late 1800s, and support our case by examining collection effort in other insects. This discovery suggests there may be relictual populations of this large, charismatic insect yet to be discovered.

Almost all the type specimens of Cacotherapia Dyar (Pyralidae: Galleriinae) are located at The National Museum of Natural History, Smithsonian Institution, Washington, DC (USNM). The type specimens and their labels were photographed, and original descriptions were reviewed to investigate the status of primary type specimens. The locality of the type species, C. nigrocinereella Hulst, is confirmed to be Utah, and not Texas as in the original description. Lectotypes are designated for C. angulalis (Barnes and McDunnough, 1918), C. flexilinealis Dyar, 1905, C. poecilostigma (Dyar, 1914), C. ponda Dyar, 1907, and C. unipuncta (Dyar, 1913) to fix and stabilize the scientific name for these species.
