The bat tick Ornithodoros kelleyi Cooley and Kohls (Arachnida: Ixodida: Argasidae) and eastern bat bug Cimex adjunctus Barber (Insecta: Hemiptera: Cimicidae) were collected from houses in Greene County, Missouri, that were previously infested by bats. Additional specimens of C. adjunctus were taken from a live big brown bat (Eptesicus fuscus (Palisot de Beauvois)) in Greene County and an evening bat (Nycticeius humeralis (Rafinesque)) in Webster County, Missouri. These records constitute only the third report of each species from the state, and the first from those counties. Distributional and host data for both species are summarized and presented. Distribution, feeding habits, and limited association with human habitations confer a low disease vector potential on both ectoparasites.

Two new species of Platynota are described and illustrated: P. subtinae, new species, from Venezuela, Bolivia, and Paraguay, and P. meridionalis, new species, from Argentina. Although both have been reared only from cotton (Gossypium sp., Malvaceae), they are suspected to be polyphagous, as are nearly all other species in the genus. Two morphological characters of the male genitalia of the new species, i.e., transtilla densely covered with large thorns and juxta deeply excavated in the middle, are most similar to each other and to Platynota stultana Walsingham, described from northwestern Mexico. The two new species are compared to Platynota stultana and P. xylophaea (Meyrick), the latter native to Argentina, with which the new species are superficially similar.

Two new species of the leafhoppers in the Coelidiinae (Hemiptera: Cicadellidae) from China are described and illustrated. They are Thagria albofascia Fan, Dai and Li (Cicadellidae: Coelidiinae: Thagriini: Thagria) and Olidiana ramosa Fan, Dai and Li (Cicadellidae: Coelidiinae: Coelidiini: Olidiana). The type specimens are deposited in the Institute of Entomology, Guizhou University, Guiyang, China (GUGC).

Two new species of the leafhopper genus Dryodurgades Zakhvatkin, D. caoi Li, Dai and Li from Gansu Province of Northern China (Palearctic part) and D. fanjingshanensis Li, Dai and Li from Guizhou Province of Southern China (Oriental part), are described and illustrated. An updated checklist and distribution of all known species of the genus are given and a key based on the male aedeagus is provided to help distinguish species of the genus.

From 2008–2010, as part of an ongoing inventory of assemblages of cavity-nesting wasps and bees of the Finger Lakes region of central New York State, we conducted trap-nest surveys at sites administered by the Finger Lakes Land Trust (FLLT): the Roy H. Park Preserve (RPP) and the Dorothy McIlroy Bird Sanctuary (DMS). Over 200 nests were provisioned by 21 species, including 12 species of wasps and 5 species of bees at RPP and 14 wasps and 2 bees at DMS. Twelve species nested at both sites, but the most common at RPP (Trypoxylon frigidum Smith, Osmia pumila Cresson, and Megachile relativa Cresson) were not among those most common at DMS (Trypoxylon lactitarse (Saussure), Ancistrocerus antilope (Panzer), Passaloecus cuspidatus Smith, and D. sayi sayi Banks). The greater species richness of bees at RPP was also reflected in a greater ratio of bee- to wasp-provisioned nests. One or more natural enemies also emerged from ∼ 20% of nests, five species of brood parasites, three parasitoids, and two that we assumed are incidental cleptoparasites. The most common species of natural enemies was Caenochrysis doriae (Gribodo), which emerged from over half of T. frigidum nests and nearly one-quarter of its nest cells. Bees tended to produce more offspring per nest, partly because of higher levels of parasitism on wasps. We compare the results to that of an earlier survey we conducted at the Montezuma Wetlands Complex located northwest of the FLLT sites.

Four species of tortricids were reared from cultivated blueberries, Vaccinium corymbosum L. (Ericaceae), from four field sites in the province of Buenos Aires, Argentina: Clarkeulia bourquini (Clarke, 1949), Clarkeulia deceptiva (Clarke, 1949), Argyrotaenia sphaleropa (Meyrick, 1909), and Platynota meridionalis Brown, 2013. These are the first records of these polyphagous tortricids on Vaccinium. Larvae were discovered primarily on the flowers, buds, and fruit of the host plant, where they fed externally.

Ptenidium kishenehnicum Shockley and Greenwalt, a new species of feather-winged beetle (Coleoptera: Ptiliidae), is described from 46 million year old Kishenehn oil shales in Montana, USA. This compression fossil is the first beetle species to be described from this formation. A checklist of known fossils and their ages is provided.

Nymphs of Leptobasis lucifer (Donnelly) were collected in shallow water in a cypress (Taxodium distichum (Linnaeus) Richard (Taxodiaceae)) dome in southern Florida. They differ from L. vacillans Hagen in Selys, the only Leptobasis species previously described, by ratio of length of antennomere 2 to antennomere 1 (1.6 in L. lucifer, 1.4 in L. vacillans), cercus length (0.13–0.17 mm in L. lucifer, 0.08–0.13 mm in L. vacillans), and length—width ratio of caudal lamellae (> 4.0 in L. lucifer, < 4.0 in L. vacillans). Leptobasis is most similar to Ischnura Charpentier and Enallagma Charpentier; a combination of characters, including head width and the arrangement of setal bases on the lateral carinae of the abdominal segments, is necessary to separate these genera.

Stinging nettle (Urtica dioica L.; Urticaceae), a Holarctic perennial herb, is a host plant of two lygaeoids of the family Heterogastridae: Heterogaster urticae (F.) in the Palearctic and H. behrensii (Uhler) in the Nearctic Region. We give the first published North American records (other than port-of-entry interceptions) of H. urticae, based on fieldwork in British Columbia in 2010 and 2011. We also give new distribution records for H. behrensii, a species of special concern in the province; it previously was known in Canada only from one site in British Columbia. Morphological characters are provided to distinguish the species. Both heterogastrids were collected from stinging nettle in British Columbia's Lower Fraser Valley and on Vancouver Island; H. urticae also was taken in the Vancouver Metro Area. The species were syntopic in two nettle colonies. We suggest that the heterogastrids'syntopy provides an opportunity to determine whether the adventive H. urticae might adversely affect the native H. behrensii.
