We describe more precise definitions for the term "eusociality" and other social systems. Our criterion eusociality is presence of castes, which are groups individuals that become irreversibly behaviorally distinct at some point prior to reproductive maturity. Eusocial societies characterized by two traits: (1) helping less-reproductive caste, (2) either behavioral totipotency only caste (facultative eusociality) or neither (obligate eusociality). define "cooperative breeding" as...
The phenological relationships between nesting behavior of a specialist, solitary bee, Dieunomia triangulifera, and the flowering its primary pollen source, Helianthus annuus, were studied for 3 yr at site in northeastern Kansas, which contained 50 000 >150 nests. Activity patterns D. triangulifera are closely synchronized with availability on nearby sunflower plants three ways: (1) each year, became active within days beginning local bloom, emergence schedule entire population nest was...
Modern advances in DNA sequencing hold the promise of facilitating descriptions new organisms at ever finer precision but have come with challenges as major Codes bionomenclature contain poorly defined requirements for species and subspecies diagnoses (henceforth, diagnoses), which is particularly problematic DNA-based taxonomy. We, commissioners International Commission on Zoological Nomenclature, advocate a tightening definition "species diagnosis" future editions bionomenclature, example,...
Lycorma delicatula (Hemiptera: Fulgoridae), the spotted lanternfly, native to China, invaded and established in northeast U.S. 2014. Since this time, populations have grown spread rapidly, invasion bridgeheads been detected mid-western states (i.e., Indiana 2021). This invasive pest presents a significant threat Californian agriculture. Therefore, proactive classical biological control program using Anastatus orientalis (Hymenoptera: Eupelmidae), L. egg parasitoid was initiated anticipation...
Many of the females first summer brood sweat bee Halictus rubicundus mate, soon vanish from nesting site, undergo diapause, and return unworn following spring to found their own nests without ever functioning as workers. Roughly half a season's foundresses may originate in this way. This finding contradicts previous assumptions regarding timing reproductive production bees offers remarkable example intraspecific social diversity; some population behave solitary while others are social. Such...
The biodiversity of insect trypanosomes is largely unknown, resulting in significant gaps the understanding pathogen evolution. A culture-independent preliminary survey trypanosomatid fauna was conducted for parasites Heteroptera (Hemiptera) from several localities Costa Rica. Trypanosomatid infections were detected by light microscopy smeared gut contents. Out 257 insects representing 6 families, found 62 cases; cultures obtained 29 new isolates. Gut material infected hosts preserved field...
When asked where to find bees, people often picture fields of wildflowers. While true for almost all species, there is a group specialized also known as the vulture that instead can be found slicing chunks meat from carcasses in tropical rainforests.
There have been four species of the cerambycid genus Xixuthrus described from Fijian archipelago; X. heros (Heer), terribilis Thomson, ganglbaueri Lameere, and heyrovskyi Tippmann. Over time, had reduced to synonymy, it suggested that was probably New Guinea rather than Fiji. We here re-establish validity terribilis, place in synonymy with it, designate a neotype for resolve both identity its geographic provenance. Diagnoses three confirmed are presented, including digital images type...
Tabanus variegatus F. 1805 has been called by the name sulcifronsMacquart 1855 for over 80 yr; T. is one of most common large horse flies attacking livestock in much southeastern U.S. Morphological, ecological, and molecular evidence indicates that a distinct species, we redescribe female describe male. The Fabricius holotype, heavily damaged after nearly 220 yr, nevertheless taxonomically sound. Morphology (size, color, palp shape, r5 wing cell shape) can usually distinguish from...
The purpose of this application, under Article 29 the Code, is to emend family-group name ANCYLINI Michener, 1944 (Insecta, Hymenoptera), a junior homonym Rafinesque, 1815 (Mollusca, Gastropoda), thereby removing homonymy between two names.It proposed that stem generic Ancyla Lepeletier de Saint Fargeau, 1841, on which hymenopteran based, be emended give ANCYLAINI, while leaving molluscan (based Ancylus Miller, 1774) unaltered.
The fulgorid name Alphina glauca (Metcalf) has been used erroneously since its inception to refer a primarily southeastern U.S. species described originally as Calyptoproctus marmoratus Spinola. Additionally, at least three undescribed from the Southwest have incorrectly identified A. glauca. holotype of not located. Since is presently multiple species, neotype designated which places into synonymy with marmoratus. We establish new genus, Scaralina, it placed, giving combination Scaralina...
Herein I summarize what is known about Cockerell's bumblebee, Bombus cockerelli Franklin, a New Mexican bumblebee species whose existence has been largely overlooked for decades because of combination rarity, geographic restriction, and taxonomic confusion. It noteworthy that the distribution covers only 777 km2, giving it smallest range any in world. There are 34 specimens, present historical details regarding their collection (dates, places, host plants), deposition, identification;...
