Anchimacheta suppletella (Zeller, 1877), n. comb. (Lepidoptera: Urodoidea: Urodidae), is transferred from Blastobasis Zeller, 1855 (Gelechioidea: Blastobasidae). Anchimacheta suppletella is redescribed, and diagnostic features are given in support of the transfer. Anchimacheta suppletella is the first species of the genus recorded from South America, and it represents the southernmost known distribution for the genus. Images of the imago and illustrations of the male and female genitalia are provided. A lectotype is designated for Blastobasis (Hypatima) suppletella Zeller, 1877.

The fossula spongiosa is a hairy attachment structure found on the apex of the fore tibia (and sometimes other legs) in several groups of cimicomorphan Heteroptera. In this study, the tibial brush setae making up the fossula spongiosa (tibial pad) of the bed bug, Cimex lectularius, were examined by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Tibial brush setae were found on all legs and are long and slender and situated in a pad at the apex of the ventral surface of the tibia. The distal end of each seta is spatulate with a smooth dorsal surface and a ventral surface with rounded protuberences. TEM analysis showed that the tibial brush setae are hollow and the base of the hollow setae are in contract with epidermal cells. Trichoid sensilla are dispersed among the tribial brush setae. As for numbers, leg I of the female has significantly more brush setae than leg II, and leg II more than leg III.

Drosophila suzukii (Matsumara) (Diptera: Drosophilidae) is a highly polyphagous invasive vinegar fly and a pest of small and stone fruits in regions where it has established. Its ability to use a wide range of food sources has likely aided in its success as an invasive species. To date, over 130 species representing 60 genera and 30 different plant families have been documented as hosts for D.suzukii. Understanding the host range of this pest is important for determining how it is able to persist locally and/or regionally when a host crop is not present. Here we describe the use of a novel host plant, Basella alba (Caryophyllales: Basellaceae), which represents the first known host from the plant family Basellaceae.

During the summers of 2011 through 2013, we used trap-nests to survey assemblages of solitary cavity-nesting Hymenoptera and their nest associates, at two sites within Finger Lakes National Forest in central New York State. The 525 occupied trap-nests produced>2,000 identifiable offspring. Nest-provisioners included 13 species of wasps (Sphecidae, Crabronidae, Vespidae, Pompilidae), of which the most common were Isodontia mexicana, Trypoxylon lactitarse, and Ancistrocerus antilope. Of the 14 species of nest-provisioning bees (Megachilidae, Colletidae), the most frequent nest occupants were Megachile campanulae, Hylaeus annulatus, Osmia pumila, and Osmia cornifrons. The most prevalent natural enemies of nesting species were Coelioxys modesta (in M. campanulae nests), sarcophagid flies (in nests of several wasp species), and Leucospis affinis (in megachilid bee nests). The study documents the presence of 10 species not found associated with trap-nests in our previous two surveys in the Finger Lakes region: Isodontia auripes, Euodynerus leucomelas, Trypoxylon tridentatum, Osmia caerulescens, O. cornifrons, Hylaeus modestus, Megachile sculpturalis, Omalus aeneus, Sapyga centrata, and Coelioxys modesta. We review the results of the trap-nesting studies we have conducted in the region since 2001, providing a compilation of data on patterns of nest-size use for the most common species. Overall, our trap-nest studies have now recorded 38 species of nest-provisioning wasps and bees, along with 14 species of brood-parasitic Chrysididae, Megachilidae, and Sapygidae.

An annotated checklist is provided for 243 species and subspecies of bees collected from or thought to occur in the state of Louisiana, where 163 are confirmed records, 46 are probable records, and 34 are possible records. We also list twelve records considered to be “dubious” because of the absence of supporting collection data and extralimital reported ranges. Data on parish localities, seasonality, and floral records are provided when available. Specimen data are provided from two separate surveys in the state, one focusing on the fauna of longleaf pine savannas and another focusing on Cajun prairie habitat in southwestern Louisiana. Data from a previous annotated checklist of bees from longleaf pine savannas (Bartholomew et al. 2006) are included, as well as online records from the Discover Life checklist (Ascher and Pickering 2016), and bee holdings of the Louisiana State Arthropod Museum (LSAM, Louisiana State University, Baton Rouge, LA).We highlight the role that this museum and similar small institutional insect collections play in documenting faunas on local and regional scales.

The fire ants of the Solenopsis geminata species-group of Trager (1991) are revised based on the morphology of worker larvae and of adult forms of workers, males, and gynes (winged or dealated members of the queen caste). The amount of intraspecific variation occurring in the adult males and gynes was equivalent to that of workers, making the taxonomic information gained from these castes no better than information from the workers. A new species, S. metallica, is described from southern Brazil, based on adult workers, adult gynes, males, and worker larvae. The following classification changes are made: S. virulens is placed in the S. virulens species-group; S. tridens and S. substituta are placed in the S. tridens species-group; S. metallica new species, S. daguerrei, S. electra, S. hostilis, S. interrupta, S. invicta, S. macdonaghi, S. megergates, S. pusillignis, S. pythia, S. quinquecuspis, S. richteri, S. saevissima, and S. weyrauchi are placed in the S. saevissima species-group; and S. geminata, S. xyloni, S. amblychila, S. aurea, S. gayi, and S. bruesi are left in the S. geminata species-group. The older classification, which designated complexes and subcomplexes, is abandoned. For the S. saevissima species-group, adults of males and gynes, as well as worker larvae, are described and diagnosed for each species. Diagnoses and keys (dichotomous and tabular) are provided for adult workers, the most commonly collected material, and distributions of the species are summarized.

The western Palearctic sawfly, Hoplocampa chrysorrhoea (Klug 1816) is recorded from North America for the first time. Specimens were taken in a Malaise trap in Oregon. The host plant is uncertain, but it probably feeds in the fruits of Prunus sp. and/or Crataegus spp. (Rosaceae).

Acleris tsuifengana Kawabe, 1992 is reported for the first time from mainland China. It is a polymorphic species with 10 different forms present in Yunnan. Details and images of several recently discovered forms are provided and discussed.

Bionomics of North American Scutelleridae are poorly known compared with the related family Pentatomidae, with host-plant relationships particularly needed for species of the scutellerid subfamily Odontotarsinae and certain species of the pentatomid genus Chlorochroa, subgenus Rhytidolomia. The odontotarsines Euptychodera corrugata (Van Duzee), Phimodera binotata (Say), and Vanduzeeina balli (Van Duzee), and the pentatomid Chlorochroa (Rhytidolomia) viridicata (Walker) are reported from field sagewort (Artemisia campestris L. subsp. caudata [Michx.] Hall. & Clems.; Asteraceae) at a site in the Nebraska Sandhills. The scutellerids were beaten from the bases of sagewort, whereas the pentatomid was swept from flower buds. Color images of the adults and new state records for C. viridicata are presented, previous biological information on the four pentatomoids is reviewed, biological attributes contributing to their apparent rareness is discussed, and the long-term protection that the Nebraska Sandhills might provide for these species is evaluated. A greater capacity for detecting the odontotarsines is needed to substantiate their use of A. campestris as a host plant and an apparent preference for Asteraceae, and to provide specimens for laboratory studies of their bionomics.

Sixeonotopsis crassicornis Carvalho and Schaffner has remained obscure since its 1974 description from Texas and has been known only from the type locality. It is newly recorded from Arkansas (two locales) on branched foldwing (Dicliptera brachiata [Pursh] Spreng.; Acanthaceae), the first plant documented as a host of this bryocorine mirid of the tribe Eccritotarsini. Branched foldwing, known from the type locality of S. crassicornis (Palmetto State Park, Gonzales County, TX), is suggested to have been the source of specimens used in the original description. Collection data are given for a recently identified specimen of the plant bug collected in 1906 from Victoria, Texas. Notes on the bug's habits, habitat, and seasonality are included, as well as a diagnosis, redescription, and discussion of its taxonomic relationship to other North American eccritotarsine Bryocorinae.
