Flies are one of four superradiations of insects (along with beetles, wasps, and moths) that account for the majority of animal life on Earth. Diptera includes species known for their ubiquity (Musca domestica house fly), their role as pests (Anopheles gambiae malaria mosquito), and their value as model organisms across the biological sciences (Drosophila(More)
Although exceptional examples of adaptation are frequently celebrated, some outcomes of natural selection seem far from perfect. For example, many hoverflies (Diptera: Syrphidae) are harmless (Batesian) mimics of stinging Hymenoptera. However, although some hoverfly species are considered excellent mimics, other species bear only a superficial resemblance(More)
A procedure for the isolation of target PCR bands from multiplex PCR products using the E-Gel iBase Power System, an E-Gel Safe Imager Real-Time Transilluminator, and E-Gel CloneWell 0.8% SYBR Safe agarose cassettes is presented. The collected isolates are suitable for direct use in sequencing reactions without need of further purification. Reductions in(More)
Animal communication signals can be highly elaborate, and researchers have long sought explanations for their evolutionary origins. For example, how did signals such as the tail-fan display of a peacock, a firefly flash or a wolf howl evolve? Animal communication theory holds that many signals evolved from non-signalling behaviours through the process of(More)
The first attempt to phylogenetically place Conopidae using molecular characters, as well as the largest molecular analysis of relationships within Schizophora (Diptera) to date, is presented. Twenty-eight taxa from 11 acalyptrate families and seven acalyptrate superfamilies are represented. Nearly 12,800 bp of sequence data from 10 genes representing both(More)
Sequence data from 420 bp of mitochondrial 12s ribosomal DNA and 490 bp of 16s rDNA were analyzed for 27 species of Syrphoidea (Diptera) and two outgroup taxa. Morphological data for the Pipunculidae were combined with the pipunculid molecular data set. A partition homogeneity test on these data sets revealed no significant incongruence. The pipunculid(More)
Uroobovella (Mesostigmata: Uropodoidea: Urodinychidae) species are among the most common mites associated with carrion-feeding Nicrophorus (Silphidae) beetles. Previous taxonomic understanding suggests that a single host generalist, U. nova, disperses and lives with Nicrophorus species worldwide (reported from at least seven host species). Using(More)
Understanding the ecology and evolutionary history of symbionts and their hosts requires accurate taxonomic knowledge, including clear species boundaries and phylogenies. Tortoise mites (Mesostigmata: Uropodoidea) are among the most diverse arthropod associates of bark beetles (Curculionidae: Scolytinae), but their taxonomy and host associations are largely(More)
