“…The branched network in Figure 8C perhaps provides a glimpse of the complex migratory network of P. flavescens, potentially spanning Asia and Africa. The appearance of P. flavescens in Japan, China, Indonesia, Sri Lanka, NE India, and southern Islands of the Indian ocean such as Amsterdam Island and Chagos Archipelago (see Figure 1; Table 1) prompts us to speculate that branching and dispersal of migrating P. flavescens emerge from all the locations that are part of a more complex migratory circuit spanning Asia, Africa and beyond (Sparrow et al, 2020). The migration significantly impacts global ecology, and its success is linked to any stressors of the climate and local ecological systems.…”

Transoceanic migration network of dragonfly Pantala flavescens: origin, dispersal and timing

The awe-inspiring multi-generational, transoceanic migration circuit of dragonfly species, Pantala flavescens stretches from India to Africa. Understanding the collective role of wind, precipitation, fuel, breeding, and life cycle driving the migration remains elusive. We identify the transoceanic migration route from years 2002 to 2007 by imposing an energetics-based time-constraint on a modified Dijkstra’s path-planning algorithm incorporating active wind compensation. The prevailing winds play a pivotal role; the Somali Jet enables migration across the Indian Ocean from Africa to India, whereas the return requires stopovers at the disappearing islands of the Maldives and Seychelles. The migration timing, identified using monthly-successful trajectories, life cycle, and precipitation data, corroborates sightings. A branched-network hypothesis connects our sighting in Cherrapunji (North-East India), the likely origin, to the known migration circuit.

“…Whereas (holometabolous) insects such as flies or butterflies use their legs immediately after pushing out of their pupal case, (hemimetabolous) insects like cicadas or dragonflies rest for several minutes in e.g. a hanging or upright position with their head, thorax and only part of their abdomen being pulled out, taking some time to harden their legs, before they bend towards and cling to the substrate to withdraw their abdomen [31,[49][50][51][52][53].…”

The arthropod cuticle offers strength, protection, and lightweight. Due to its limit in expandability, arthropods have to moult periodically to grow. While moulting is beneficial in terms of parasite or toxin control, growth and adaptation to environmental conditions, it costs energy and leaves the soft animal's body vulnerable to injuries and desiccation directly after ecdysis. To investigate the temporal change in sclerotization and pigmentation during and after ecdysis, we combined macrophotography, confocal laser scanning microscopy, scanning electron microscopy and histological sectioning. We analysed the tarsal and mandibular cuticle of the blue emperor dragonfly to compare the progress of tanning for structures that are functionally involved during emergence (tarsus/tarsal claws) with structures whose functionality is required much later (mandibles). Our results show that: (i) the tanning of the tarsal and mandibular cuticle increases during emergence; (ii) the tarsal cuticle tans faster than the mandibular cuticle; (iii) the mandibles tan faster on the aboral than on the oral side; and (iv) both the exo- and the endocuticle are tanned. The change in the cuticle composition of the tarsal and mandibular cuticle reflects the demand for higher mechanical stability of these body parts when holding on to the substrate during emergence and during first walking or hunting attempts.

Diversity, Status and Phenology of the Dragonflies and Damselflies of Cyprus (Insecta: Odonata)

2021

Based on literature data, unpublished material and the results of the year-round monitoring at selected sites island-wide by the Cyprus Dragonfly Study Group since 2013, we acquired an excellent knowledge of the diversity and status of the Odonata of Cyprus. Altogether, 37 species are on the island’s checklist. Ischnura pumilio, Aeshna affinis and Brachythemis impartita were only very rarely recorded in the past but are considered to be no longer present. The single record of Calopteryx virgo from 1930 is in our opinion a misidentification and has been removed from the checklist. The island has a rather impoverished odonate fauna compared to neighbouring countries. There are no endemic species, but the island is home to some range of restricted species of which Ischnura intermedia is the most important. Flight seasons determined for the 31 species with sufficient data were generally found to be longer than reported for other countries in the Eastern Mediterranean. This may be due to intensive year-round monitoring but could also result from Cyprus’ warmer climate. Very wide annual variations were found in the abundance of all species over the seven years and show an almost immediate response to the wide fluctuations in Cyprus’ annual rainfall levels.
