“…Moreover, the double influence on wing morphology of life history traits and of the conditions at the location where the individual developed creates confounding effects and reduces the power of wing morphology to determine the geographical origin. Finally, morphological differences are also often associated with genetic structure (Villemant et al 2007, Francoy et al 2011, Vicente et al 2011, Neto et al 2013. However, previous studies found no evidence for genetic structure either in relation with geographical origin (Hondelmann et al 2005, Raymond et al 2013b, or with overwintering strategy (Raymond et al 2013a) in E. balteatus.…”

“…This method is based on the principle that local conditions can shape the development of animals (Bateson et al 2004), and that different environmental pressures can lead to morphological differences (Alibert et al 2001, Francoy et al 2011. Morphology could thus reveal the local conditions that prevailed during the development of the organism, and the geographical origin associated to these local conditions.…”

“…Landmark-based geometric morphometrics offer better discrimination capabilities than classical morphometrics (Rohlf and Marcus 1993, Bookstein 1996, Villemant et al 2007 as they make it possible to study the shape in addition to the size of organisms. Geometric morphometrics and in particular wing geometric morphometrics have already been used in insect taxa to characterize and identify populations from different geographical origin (Alibert et al 2001, Camara et al 2006, Francoy et al 2011, Gaspe et al 2012). However, geometrical morphometrics have rarely been used to asses issues related to migration in insect species (but see Francuski et al 2013).…”

Ecosphere 5(7):88. http://dx.doi.org/10.1890/ES14-00075.1Abstract. Migration and population dynamics are important in organisms that provide ecosystem services as they determine the occurrence of individuals in a given place at a given time, which, in turn, determines the efficiency of the service provided. To design appropriate landscape management strategies to improve the efficiency of biological control, it is essential to know the origin of beneficial insects that colonize agricultural fields. However, studying migration dynamics in insects is complicated by their small size and short life span which largely prevent the use of conventional techniques based on capture-markrecapture, or remote sensing.Stable isotopes and morphological characters are intrinsic markers that can be used to infer the geographical origin of many organisms including insects. In this study, we first determined whether the hydrogen isotopic ratio and the wing morphometrics are appropriate markers to study the spring migration dynamics of a major aphidophagous hoverfly species (Episyrphus balteatus). To this end, we assessed the magnitude of variation of these indicators in seven populations along a north-south gradient in Western Europe. Second, we used the two markers in E. balteatus individuals collected in a French agricultural landscape over the course of the spring to assess the proportion of immigrants from southern regions and the period of immigration.Our results revealed uncertainties associated with the use of the hydrogen isotopic ratio and wing morphometrics, but showed that the spring population of E. balteatus in Western France very likely comprises mainly local individuals, with the probable arrival of some immigrants from nearby regions located further south. The low proportion of immigrants in the spring population has important implications for the biological control provided by E. balteatus in terms of landscape management strategies.

“…Dujardin et al 2003). Recently, geometric morphometric approaches have shown higher statistical power compared to traditional morphometrics for species separation (Bookstein 1991;Zelditch et al 2004;Francoy et al 2011;Zinetti et al 2013). By eliminating the effect of size, statistical comparison of landmarks used in geometric morphometrics can reveal differences of actual shapes or forms with greater power of discrimination (Mitteroecker and Gunz 2009).…”

“…By eliminating the effect of size, statistical comparison of landmarks used in geometric morphometrics can reveal differences of actual shapes or forms with greater power of discrimination (Mitteroecker and Gunz 2009). In bees, geometric morphometrics of the forewing has been capable of discriminating operational taxonomic units (Aytekin et al 2007;Francoy et al 2008Francoy et al , 2011Kandemir et al 2011). Importantly, such identification seems to conform to those based on molecular markers (Francoy et al 2012;Oleksa and Tofilski 2015).…”

Identification of cryptic species and morphotypes in male Euglossa: morphometric analysis of forewings (Hymenoptera: Euglossini)

-Males of sibling orchid bees Euglossa viridissima and Euglossa dilemma are morphologically cryptic, except for the number and shape of mandibular teeth. An alternative morph of E. viridissima has a third tooth similar to males of E. dilemma . We used this model system to evaluate the potential of wing morphometrics for the resolution of these groups. We found differences in the size characters of forewings of E. viridissima and E. dilemma albeit with substantial overlapping amongst them. However, geometric morphometrics of forewing vein intersections separated both species and, to a lesser extent, morphotypes. A discriminant analysis of the shape of the radial cell showed separation between all three groups, too, albeit with higher misclassification between E. viridissima and E. dilemma . We show that sibling cryptic species and morphotypes can be identified by geometric morphometrics, supporting its application with other methods as powerful aids to infrageneric taxonomy in bees.orchid bee / cryptic species / morphotypes / geometric morphometrics / forewing

Phenotypic divergence is an important consequence of restricted gene flow in insular populations. This divergence can be challenging to detect when it occurs through subtle shifts in morphological traits, particularly in traits with complex geometries, like insect wing venation. Here, we employed geometric morphometrics to assess the extent of variation in wing venation patterns across reproductively isolated populations of the social sweat bee, Halictus tripartitus . We examined wing morphology of specimens sampled from a reproductively isolated population of H. tripartitus on Santa Cruz Island (Channel Islands, Southern California). Our analysis revealed significant differentiation in wing venation in this island population relative to conspecific mainland populations. We additionally found that this population‐level variation was less pronounced than the species‐level variation in wing venation among three sympatric congeners native to the region, Halictus tripartitus , Halictus ligatus , and Halictus farinosus . Together, these results provide evidence for subtle phenotypic divergence in an island bee population. More broadly, these results emphasize the utility and potential of wing morphometrics for large‐scale assessment of insect population structure.
