“…They also indicated by examining intra-and inter-population genetic distances, in agreement with [44,46], that the species S. calcitrans may in fact contain several cryptic species. Kneeland et al (2015) [47] also studied the genetic diversity of S. calcitrans on a global scale. Specimens from different biogeographic regions were analysed with the AFLP technique.…”

In the subfamily Stomoxyinae there are currently 18 recognized Stomoxys species, plus two subspecies. Most Stomoxys knowledge was gained through studies with S. calcitrans, a cosmopolitan species, economic pest, and vector. Other Stomoxys spp. are known only from a few trapped adult specimens. Herein, the Stomoxys spp. have been grouped by their ecological diversity, global distribution, and phylogeny and phylogeography. Seven species are dependent to some degree on humans and their activities, particularly animal production. Eleven species are dependent on wildlife to some degree for their development, and little is known about their biology in many cases. Global distributions include one cosmopolitan species (S. calcitrans), twelve species found only in Africa, four species only in Asia, and one species (S. sitiens) in Africa and Asia. Most genetic studies on Stomoxys calcitrans showed little variation in North America, possibly due to the adults’ long range flight capability. Phylogeographic analysis of S. calcitrans showed a differentiation between Oriental populations (first lineage) and populations from Afrotropical, Palearctic, Nearctic, Neotropical and Oceanian regions (second lineage). Genetic studies were followed by sequencing of the Stomoxys calcitrans genome and phylogenetic studies of the Stomoxys genus using 10 of the known species. Phylogenetic relationships were established.

“… 87 , 88 High levels of gene flow among Nearctic, Neotropical, Pale-arctic, and Australian biogeographic regions suggest that population expansion, and the majority of genetic diversity, occurs within groups, and much less so between groups. 89 Stable fly genetics have, as a result, been characterized as being panmictic, with no isolation by distance or across geographical barriers. 89 As with regional dispersal, global dispersal appears to be most limited by temperature- and moisture-related barriers relating to latitudes, elevations, and deserts.…”

Although the movement of stable fly, Stomoxys calcitrans (L.), has been studied, its extent and significance has been uncertain. On a local scale (<13 km), fly movement occurs between host animals and resting sites to feed and mate, mainly at on-farm locations where herbivorous livestock regularly congregate. Small numbers emigrate from livestock congregation sites in search of other hosts and oviposition substrate, mostly within <1.6 km. Such local movement occurs by flight ~90 cm above ground, or with moving livestock. While stable flies are active year-round in warm latitudes, cold winters in temperate areas result in substantial population and activity declines, limiting movement of any sort to warmer seasons. Long-distance dispersal (>13 km) is mainly wind-driven by weather fronts that carry stable flies from inland farm areas for up to 225 km to beaches of northwestern Florida and Lake Superior. Stable flies can reproduce for a short time each year in washed-up sea grass, but the beaches are not conducive to establishment. Such movement is passive and does not appear to be advantageous to stable fly’s survival. On a regional scale, stable flies exhibit little genetic differentiation, and on the global scale, while there might be more than one “lineage”, the species is nevertheless considered to be panmictic. Population expansion across much of the globe likely occurred from the late Pleistocene to the early Holocene in association with the spread of domesticated nomad livestock and particularly with more sedentary, penned livestock.

“…Based on our observations, the Platte River caddisfly appears to be a weak flier, and genetic techniques can provide insight into a species' dispersal ability in the absence of directly observing significant dispersal events (Clobert et al 2001;Kelly et al 2002;Blakely et al 2006). Amplified fragment length polymorphism (AFLP) has been used to determine the amount of gene flow within a species (Kelly et al 2002;Clark et al 2007;Kneeland 2011). Therefore, it is appropriate that AFLP be used to test the hypothesis that there is breeding among extant Platte River caddisfly populations.…”

The Platte River caddisfly (Ironoquia plattensis Alexander and Whiles 2000) was recently described from a warm-water slough along the Platte River in central Nebraska and was considered abundant at the type locality. Surveys of 48 sites in 1999 and 2004 found eight additional sites with this species on the Platte River. The caddisfly was not found at the type locality in 2004 and one additional site in 2007, presumably because of drought conditions. Because of its apparent rarity and decline, the Platte River caddisfly is a Tier I species in Nebraska. For this project, surveys for the caddisfly were conducted at 113 new and original sites primarily along the Platte, Loup, and Elkhorn Rivers between 2009 and 2011. These surveys identified 30 new sites with the caddisfly. Larval densities were quantified at a subset of inhabited sites, and there was a large variation of densities observed. Seven sites on other Nebraska drainages were found to support morphologically similar caddisflies, presumably the Platte River caddisfly. Because of the discovery of populations outside the Platte River drainage, amplified fragment length polymorphism (AFLP) was used to determine the amount of genetic variability and breeding among sites on the Platte, Loup, and Elkhorn Rivers. Analysis of molecular variance (AMOVA) suggested moderate gene flow among the three river systems and that there was more genetic variation within populations than between populations. Differentiation, but not total divergence, was exhibited by the northernmost population from the Elkhorn River. Because it may be considered an indicator species and is vulnerable to ongoing habitat loss and degradation, all Platte River caddisfly populations should be conserved.
