  • Migratory Dragonflies » Identification Guide - Spot-winged Glider (Pantala hymenaea)
    Individuals move north from tropics during summer farther north in East than West usually earlier than Wandering breeding along the way Migratory flights south in fall presumably their offspring but poorly known SIMILAR SPECIES Wandering Glider Pantala flavescens same size shape and behavior but paler more yellow to orange and without dark spots at hindwing bases various saddlebags Tramea spp similar size and shape but hindwing markings extend entire width of wing may be quite narrow or much larger than spot on Spot winged SIMILAR TROPICAL SPECIES The next four tropical species are fliers with dark markings at wing bases All are smaller than Pantala gliders and the dark markings in all are located more at the front of the wing base Abdomens are spindle shaped in males wider in middle than at either end more parallel sided in females as in Pantala gliders Garnet Glider Tauriphila australis dark hindwing markings small slightly larger in female abdomen red in male duller in female with dark central stripe near tip Arch tipped Glider Tauriphila argo much like Garnet Glider but red male or orange female abdomen unmarked with black stripe at tip basal wing spots a bit larger not as large

    videos note the use of the legs to grab the pray and bring it to the mouthparts while in flight Dragonfly Eggs Hatching Shows oviposition by tapping the abdomen on the water followed by amazing close ups of eggs developing and hatching into a prolarva which molts almost immediately into a 1st instar nymph Dragonfly Larvae Hunting Backswimmers Fantastic close up that shows the operation of the rectal gills full speed shots of strikes at prey and slow motion replays showing labium extending and some slightly gory footage of captured bugs being throuughly munched Dragonfly Laying Eggs in a Pond Shows a female laying eggs by tapping the tip of her abdomen repeatedly against the surface of the water a behavior that people sometimes confuse with drinking Dragonflies mating Note that as the female lays her eggs in the water the male follows and guards her to prevent any other males from mating with her Also shows close ups of tandom pair copulating in the wheel position Fascinating dragonfly in UltraSlow Flight The ability of the dragonfly s 4 wings to each move independently of the others is seen clearly here Green Darner Dragonflies laying Eggs Shows oviposition by inserting

    anywhere in North America including Mexico and are willing to collect adults of any of the five main migratory species Common Green Darner Black Saddlebags Wandering Glider Spot Winged Glider or Variegated Meadowhawk Specimen Preservation Specimens to be used for fat analysis should be air dried NOT preserved in acetone the usual method for odonate preservation Each specimen to be processed should be placed in its own individual envelope so that if any body parts break off after processing they can still be associated with the correct individual Specimens should be dried until the legs and abdomen are stiff and each should have one intact forewing and hindwing Drying may be done in several different ways depending on the equipment you have available Place the envelopes in an oven or toaster oven on a very low warm setting i e 100 110F for several hours Place the envelopes in a cardboard box with a 75 100W incandescent bulb extending through a hole in the top for several hours Place the envelopes in a drying oven set at 45C for 24 48 hrs Envelopes can also be dried in direct sunlight i e on the dashboard of a car or with a hair dryer but this will take much longer and may result in incomplete drying Dried specimens can be sent to Dr Mike May at Department of Entomology Thompson Hall 96 Lipman Drive Rutgers University New Brunswick New Jersey USA 08901 8525 Please use a small box with enough padding that the specimens won t be crushed during transit Additional Studies MDP may institute a variety of additional studies conducted across a shorter time span than Pond Watch and Migration Monitoring to address specific research questions as they arise For example we recently completed an analysis of stable hydrogen isotope

    engage citizen scientist volunteers to regularly monitor and report on the seasonal distribution of five of the best known migratory dragonfly species at wetland sites throughout North America Common Green Darner Black Saddlebags Spot winged Glider Wandering Glider and Variegated Meadowhawk Participants will visit local ponds of their choice and make repeated visits over time to collect relevant field data on the annual movements of target species and the biodiversity at their site For more information or to volunteer please visit the Dragonfly Pond Watch project webpage Stable Isotope Project The Stable Isotope Project investigates patterns of reproduction emergence and movement among migrant species at different latitudes Participants will help us assess connectivity of migratory dragonfly populations using stable isotope signatures Isotopes are different forms of one chemical element each with a slight variation in atomic structure These isotopic forms vary characteristically with latitude For dragonflies an isotopic signature can be generated by measuring the ratio between stable isotopes of hydrogen a component of the waters in which the nymphs live during development traces of which remain locked into the wing tissue of the adult after emergence By comparing the hydrogen isotope ratio in its wings to that of the water body where the insect was captured researchers can get an indication of how far a captured dragonfly has moved from its emergence site Isotope data will increase our understanding of the points of origin of dragonflies in a mass flight better delineate southern and northern endpoints of migration and help distinguish migratory individuals from residents The first round of analysis for the isotope project was successful Thank you to all the citizen scientists who collected and submitted specimens Based on the information gathered the Partnership s Isotope Project will soon be changing direction Please stay tuned for updates to
