The oviposition, eggs, emergence of first instar larvae, and larvae of Mallophora orcina (Wiedemann, 1828) are described and compared with those of Mallophora spp., Megaphorus spp., and other species of robber flies. Oviposition occurred on vegetation 1–3 m above the ground with approximately 188–323 eggs deposited in layers in a chalky-white albumin. The eggs are elongate and initially glistening white. They turn a dark metallic color on the end where larvae emerge from. Upon emergence the larvae drop to the ground where they bury themselves in the soil. Larvae are shiny white, dorsoventrally flattened, tapering at each end, with a distinct head, 3 thoracic segments, and 9 abdominal segments. The separation between most segments is not visible or clearly delineated.

Pseudodineura parva (Norton) (Hymenoptera: Tenthredinidae: Nematinae), Phytomyza multifidae Sehgal (Diptera: Agromyzidae), and Cerastis tenebrifera (Walker) (Lepidoptera: Noctuidae) were reared from wood anemone (Ranunculaceae: Anemone quinquefolia L.), and Monophadnus aequalis MacGillivray (Hymenoptera: Tenthredinidae: Blennocampinae) from sharp-lobed hepatica (A. acutiloba (DC.) G. Lawson) for the first time. The rearing of P. multifidae represents a new U.S. record, and the sawfly records extend the known range of both species south to northwestern Alabama. Details of rearings of all four species are provided, along with descriptions of the sawfly larvae. Two parasitoids, Pnigalio flavipes (Ashmead) and P. pallipes (Provancher) (Eulophidae), were reared from Phytomyza multifidae.

Historical and recent studies of Boulder County, Colorado (USA) bees (Hymenoptera: Anthophila) illustrate the potential and the pitfalls of using comparative collection data to evaluate faunal composition and change over time. A compilation of bee records from Boulder County (Scott et al. 2011) is used as a basis for re-examining the comparison of an historical data set (Cockerell 1907) with a recent one (Kearns and Oliveras 2009a,b). Despite numerical comparability reported by Kearns and Oliveras, the taxonomic and behavioral composition of these data sets differ markedly from each other and, in different ways, from that of the subset of bee species common to both and from the total fauna documented from Boulder County. The rank order of species richness across bee families and across cohorts of bees with different social behaviors and feeding preferences do not covary among data sets: taxonomically, colletids, andrenids and megachilids are relatively under-represented in the more recent data set, in which halictids are better represented than any other family. Behaviorally, parasitic and oligolectic solitary species are less well represented in both datasets, the paucity of Andrena Fabricius spp. being especially conspicuous in the more recent of the two, which is dominated by polylectic social bees. Ensemble comparisons of raw species richness may mask differences in the readiness with which bees with different taxonomic affiliations, social behaviors, and degrees of host plant specificity lend themselves to being sampled, and possibly to their appearing to undergo faunal turnover. When these behaviors are taken into account, these comparisons imply either (1) impacts, in descending order of severity, on parasitic bees, oligolectic solitary bees, and polylectic solitary bees or (2) the relative ineffectiveness with which these classes of bees are sampled with generalized pan- or bowl-trapping techniques. Seasonally limited summer sampling protocols may favor polylectic social bees, as reflected in halictids' being disproportionately well-sampled relative to andrenids, which account for a majority of early season oligolectic solitary bees—ironically those of potentially greatest interest when evaluating the stability of pollinator faunal diversity. By virtue of their abundance and protracted flight seasons, in contrast, eusocial bees appear to be among the most readily sampled, though potentially less relevant to the purposes of evaluating the integrity of animal-pollinated plant communities.

The lepidopteran fauna of Massachusetts' offshore islands (USA), particularly Martha’s Vineyard and Nantucket, has been well characterized, and comprises intact assemblages of disjunct, regionally rare, habitat-specialized, and otherwise threatened species that have declined elsewhere in New England. These include the only persistent and extant population of Eacles imperialis Drury (Saturniidae: Ceratocampinae) in New England, one of at least three ceratocampines to have undergone partial or total extirpation from the region. Examining historical and recent records within two groups—Saturniidae and Sphingidae—that have exhibited varying degrees of flux over time, we compare these islands and identify taxonomic and ecological components of their faunas that appear historically volatile. After reviewing suspected agents of these declines, including the introduced generalist parasitoid Compsilura concinnata (Diptera: Tachinidae), we present preliminary tachinid capture data which suggest that C. concinnata has not been established where E. imperialis persists.

The largely New World genus Crophius Stål, revised status, and Mayana Distant, revised status, are resurrected from synonymy with the genus Anomaloptera Amyot and Serville, which is restricted to contain only the type species, A. helianthemi Amyot and Serville, from the western Mediterranean Region. Mayana, previously also considered a junior synonym of Crophius, is resurrected to contain M. costatus Distant, the type species, M. diruptus Distant, and M. formosus (Van Duzee), new combination, transferred from Crophius. Neocrophius, new genus, is established to accommodate Neocrophius heidemanni (Van Duzee), new combination, the type species, transferred from Crophius, and Neocrophius singularis (Brailovsky and Barrera), new combination, transferred from Anomaloptera. The genera Crophius, Mayana, and Neocrophius are described and diagnosed and dorsal habitus images and a key are provided to help distinguish the nine New World genera.

Pseudalbuginosus, a new subgenus of Aedes Meigen, is characterized and diagnosed. Aedes grjebinei Hamon, Taufflieb, and Maillot is removed from the subgenus Aedimorphus Theobald and placed in the new monotypic subgenus Pseudalbuginosus on the basis of a critical study of all known specimens. The adult male and the male genitalia of Ae. (Pseudalbuginosus) grjebinei are described, with the illustration of the genitalia and images of the proboscis and maxillary palpi. Its affinity to other subgenera of the genus Aedes is discussed. Information on type data, distribution, bionomics, medical importance and a taxonomic discussion of this species are presented.

Orius sibiricus Wagner, a dark-colored minute pirate bug widespread in the Eurasian Steppe, is recorded from sites near the Yukon River in Yukon, Canada. This species is distinguished from the melanic phenotype of Orius diespeter Herring by the more deeply and uniformly punctured dorsum, the subangular anterolateral angles of the pronotum of the female, the lack of denticles on the forefemora of the male, the entirely dark embolium, and the shape of the paramere. Collection sites for O. sibiricus in Yukon are in ecoregions that contain sun-warmed steppe in or near East Beringia. The species has also been collected in eastern Siberia from steppe sites within the boundaries of West Beringia. Specimens of O. sibiricus from East Beringia and West Beringia have very similar genitalic structures. Orius sibiricus has been collected from the plant genera Artemisia, Caragana and Spiraea, as well as from unidentified herbaceous vegetation. The geographical distribution of O. sibiricus suggests a relatively recent dispersal across the Bering Land Bridge.

Banasa tumidifrons Thomas and Yonke is a little-known stink bug of the nominotypical tribe of the subfamily Pentatominae. Described from California, Idaho, and Oregon, it since has been recorded only from Washington State. Adults are known from juniper (Juniperus), but it is not known whether junipers support the pentatomid's nymphal development. From 2012 to 2014, nymphs and adults were collected from Rocky Mountain juniper (J. scopulorum) in natural communities and ornamental plantings at 18 sites in five states: Colorado, Kansas, Nebraska, South Dakota, and Wyoming; all are new state records. Nymphs of all instars (I–V) were found on female plants of the dioecious J. scopulorum in early July and instars II–V in early to mid-September. Juniperus scopulorum is considered a host plant in a restricted sense of the term: a plant on which nymphs feed and develop. Occasionally present on junipers were fifth instars of three other pentatomids: B. euchlora Stål (Wyoming is a new state record), Thyanta calceata (Say), and T. custator accerra McAtee.

The genus Isometocoris Carvalho and Sailer is reviewed and I. penicillus, new species, from Brazil is described. Diagnoses of the genus and included species I. blantoni Carvalho and Sailer and I. penicillus, n. sp., are given; a color adult habitus photo of both Isometocoris species, male genitalic drawings of Isometocoris penicillus n. sp., and scanning electron micrographs of selected structures of I. blantoni are provided; and an identification key is given to help distinguish the two included species. Isometocoris is transferred from the subfamily Psallopinae to the Cylapinae, where it is placed in the tribe Fulviini. Psallopinae is reduced to tribal level (Psallopini, new status) within the Cylapinae, and relationships among Cylapinae, Isometopinae, and Psallopinae are discussed.
