Dragonflies in the Algarve

This summer, I went somewhat deeper into exploring the dragonflies of the Algarve. Portugal is home to close to 70 species, the majority of which can be found here in the south. This includes several species restricted to Iberia- and a few areas around the Mediterranean. Namely dragonflies of African origin have begun colonising southern Europe in the last years and decades - some, like the Broad Scarlet (Crocothemis erythraea) have long reached central Europe. Violet Dropwing (Trithemis annulata) is already among the commenest dragonflies here and is found in rocky pools or river sections (most rivers and streams dry out at least partly here in summer) in hot areas with less vegetation. It shares habitat with its sibling species, the Orange-winged Dropwing (Trithemis kirbyi) first recorded in Portugal only in 2016 (link) so one of the most recent additions to Portugals Odonata -Fauna. I was surprised finding it at more than half a dozen different- and new locations in the central- and eastern Algarve over the past two month! So spreading rapidly, it seems. Another speciality we have here in the Algarve is the Ringed Cascader (Zygonyx torridus) known to occur in Portugal only at one single spot in the west Algarve, were we found it easy to see but difficult to photograph. I include here a number of photos taken during the past weeks. The camera I used is a small travel zoom camera from Panasonic with Leica optics: Panasonic DMC-TZ70 in macro mode. Birds are still my specialty but I like not to be ignorant of the many aspects of wildlife we encounter when being in the field.

[Post edit:] Today (Aug., 27th) on the bordwalk back from Faro-beach, we noticed several large brown dragonflies hovering above the dunes and salt marsh (c. 20 Ind. in total) and I managed to get this record shot of one Ind. perched: Vagrant Emperor (Anax ephippiger) female. Amazing! This was a migratory event and they were apparently heading north!

Red-veined Darter (Sympetrum fonscolombii) mature male. Foia / Monchique, 08-August-2020. A dragonfly known to every birdwatcher here. At the cape area of Sagres, it can be extremely numerous during autumn (bird) migration, sometimes reaching hundred thousands (!) of Ind./day in the area, on northbound migration.
