Jellyfish and sea jellies are the informal common names given to the medusa-phase of certain gelatinous members of the subphylum Medusozoa, a major part of the phylum Cnidaria. Jellyfish are mainly free-swimming marine animals with umbrella-shaped bells and trailing tentacles, although a few are anchored to the seabed by stalks rather than being mobile. The bell can pulsate to provide propulsion for highly efficient locomotion. The tentacles are armed with stinging cells and may be used to capture prey and defend against predators
Tot 35-44mm, Ab 20-30mm, Hw 24-30mm.\nOne of the larger Sympetrum species. In the field, males may be noticed because they seldom become as deeply red as other species and have a rather parallel-sided abdomen.\nHabitat: Wide range of places, especially preferring warm, stagnant waters. These are often shallow and bare, this species being a pioneer of newly created ponds. Occasionally in flowing or brackish water.\nFlight Season: May be seen all year in the Mediterranean. In Northern Europe, appears from early June, becoming abundant in July and flying into November. One of the last dragonflies to be encountered in autumn.\nDistribution: Common in most of our area, becoming less common relative to S. vulgatum in a north-easterly direction. Extends to Japan. Migrations are often seen and are sometimes massive.\n\nThis is a common Species in the Netherlands.

Tot 36-45mm, Ab 23-38mm, Hw 28-33mm, about the size of Sympetrum striolatum.\nIdentification:\nThe common, small Orthetrum of flowing water throughout Europe. The Keeled Skimmer is characterized by its rather small size, fairly slender tapering abdomen and large pterostigma (around 4mm long).\nBehavior:\n Normally sits on vegetation, seldom on the ground.\nOccurrence:\nCommon around the Mediterranean, but generally local in central and Southern Europe.\nHabitat:\nRunning waters, such as streams and ditches. In north of range mainly runnels in boggy areas.\nFlight Season: \nFrom April to November; most abundant from June to August.\n\nThe Species is quite local in the Netherlands in the described Habitats. This Picture is made on the Veluwe in begin of August 2021 along a small Brook.
