|Erythromma (Brighteyes) is a genus
with only three species, all with a Euro-asian distribution. The genus
has previously been considered to host only two species, both with males
having red eyes. These are Erythromma najas (Large Redeye) and E. viridulum
(Small Redeye). A third species, E. lindenii (Blue-eye) has been added
due to similarities in the genes, but more obvious also in behaviour and
the males upper appendages, with the two other species. As this species
does not have red eyes, the name Brighteyes has replaced the name Red-eyed
The two Redeye-species looks a lot
like Bluets (Coenagrion and Enallagma species), but they are all black
on top of backside of the head. Only young individuals may have faint postocular
spots. The Blue-eye has very narrow postocular spots, compared to Coenagrion,
but also compared to Enallagma cyathigerum, which it probably resembles
Erythromma lindenii (Selys, 1840),
the Goblet-marked damselfly, is a medium-sized (length 30 - 36 mm) blue-and-black
(or green-and-black) damselfly in the pond damselfly family (Coenagrionidae).
It's a fairly common species in the South and West of Europe but is not
found in the British Isles, Scandinavia and Eastern Europe. Erythromma
lindenii was previously known as Coenagrion lindenii and Cercion lindenii.
The Goblet-marked Damselfly is also known as the Blue-eye. It's an easily
recognized species, with its wide antehumeral stripes, narrow postocular
spots, the male's very bright-blue eyes. He has very long and curved appendages,
and the spear-shaped marks on S3-S6 of his abdomen. The female is most
readily distinguished from the similar Enallagma cyathigerum (which has
comparably wide antehumerals) by the absence of a vulvar spine underneath
Erythromma lindenii has only small
postocular spots on the head, not round as other similar looking genera
, but rather thin lines that may be connected across the head. Male E.
lindenii very much looks like a Enallagma cyathigerum, but they have longer
upper appendages and two dark stripes on side of thorax where E. cyathigerum
only have one. The black marking on top of 2nd abdominal segment is also
much larger , covering most of that segment's lenght. The markings on the
3rd to 6th segment are long with a "lanceolated" shape. The female E. lindenii
has a quite unique coloration, green-yellow but with a hue of blue on the
side of the middle of the abdomen.
It can also be found in Asia: Russian
Federation and it is also found in Africa.
Erythromma lindenii has three subspecies:
Erythromma lindenii lacustre
Erythromma lindenii lindenii
Erythromma lindenii zernyi
Erythromma lindenii is found in southwest
and southern Europe and is common around the Mediterranean and in parts
of southeast Europe. The species is slowly expanding northwards and does
not seem to be threatened. Future threats to the habitat include water
pollution, especially in man-made areas that is already at marginal suitability.
