The chelal moveable digit in Carpoglyphus lactis (Linnaeus), Glycyphagus domesticus (DeGeer), and Tyrophagus putrescentiae (Schrank) from UK beehives is described using quantitative measures within a 2D mechanical model. The location of maximum jerk on the profile of the chelal moveable digit indicates the end of the mastication surface, which in these mites is confirmed to be just before the theoretical cut-off point for a functioning chewing `machine`. All three species should be able to grasp yeasts, spores and mycelial hyphae in the hive. The moveable digit of C. lactis may be designed to enable pollenophagy. The mastication surface is 21.3 μm in C. lactis, 18.8 μm in G. domesticus, and 17.2 μm in T. putrescentiae. The wild-collected C. lactis shows the smallest chelal moveable digit tip velocity ratios (i.e., the lowest relative length of input to output moment arms). Glycyphagus domesticus has the most primitive geometry of its chela. The depth of the moveable digit matches the inferred resistive forces applied by the mite to food at that point. Condylar and moveable digit strengthening by sclerotisation is associated with eating tougher food. Effective chelal gape is 28.7 μm in C. lactis, 25.9 μm in G. domesticus and 24.8 μm in T. putrescentiae. Maximum food fragment size grabbed by the chela is estimated as 7786 μm3 in C. lactis, 5348 μm3 in G. domesticus and 4703 μm3 in T. putrescentiae. Morsel size pre-ingestion is estimated as 4031 μm3 in C. lactis, 5228 μm3 in G. domesticus and 4246 μm3 in T. putrescentiae. Under reasonable assumptions one of these mites might be able to excavate its own body volume equivalent in about one hour.

“…The complete mt genomes that contain more variants provide more information than partial mt gene sequences to help scientists resolve phylogenetic relationships and infer species evolution [ 15 , 16 , 17 ]. The mt genome of insects and mites generally contains 13 protein genes, 22 tRNAs, 2 rRNAs, and a control region [ 18 , 19 , 20 ]. In this study, the complete mt genome was assembled, and the basic characteristics of P. casei mt genes were studied, focusing on the comparison of the PCGs between P. casei and P. megastigmata .…”

Piophila casei is a flesh-feeding Diptera insect that adversely affects foodstuffs, such as dry-cured ham and cheese, and decaying human and animal carcasses. However, the unknown mitochondrial genome of P. casei can provide information on its genetic structure and phylogenetic position, which is of great significance to the research on its prevention and control. Therefore, we sequenced, annotated, and analyzed the previously unknown complete mitochondrial genome of P. casei. The complete mt genome of P. casei is a typical circular DNA, 15,785 bp in length, with a high A + T content of 76.6%. It contains 13 protein-coding genes (PCG), 2 ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and 1 control region. Phylogenetic analysis of 25 Diptera species was conducted using Bayesian and maximum likelihood methods, and their divergence times were inferred. The comparison of the mt genomes from two morphologically similar insects P. casei and Piophila megastigmata indicates a divergence time of 7.28 MYA between these species. The study provides a reference for understanding the forensic medicine, taxonomy, and genetics of P. casei.

Changes in the functional shape of astigmatan mite moveable digit profiles are examined to test if Tyrophagus putrescentiae (Acaridae) is a trophic intermediate between a typical micro-saprophagous carpoglyphid (Carpoglyphus lactis) and a common macro-saprophagous glycyphagid (Glycyphagus domesticus). Digit tip elongation in these mites is decoupled from the basic physics of optimising moveable digit inertia. Investment in the basal ramus/coronoid process compared to that for the moveable digit mastication length varies with feeding style. A differentiated ascending ramus is indicated in C. lactis and in T. putrescentiae for different trophic reasons. Culturing affects relative investments in C. lactis. A markedly different style of feeding is inferred for the carpoglyphid. The micro-saprophagous acarid does not have an intermediate pattern of trophic functional form between the other two species. Mastication surface shape complexity confirms the acarid to be heterodontous. T. putrescentiae is a particularly variably formed species trophically. A plausible evolutionary path for the gradation of forms is illustrated. Digit form and strengthening to resist bending under occlusive loads is explored in detail. Extensions to the analytical approach are suggested to confirm the decoupling of moveable digit pattern from cheliceral and chelal adaptations. Caution is expressed when interpreting ordinations of multidimensional data in mites.
