|Sympetrum is a genus of small to
medium sized skimmer dragonflies, known as darters in the UK and as meadowhawks
in the North America. There are more than 50 species, predominantly living
in the temperate zone of the Northern Hemisphere; no Sympetrum are native
Sympetrum eroticum (Selys, 1883)
is a small Dragonfly, which usually does not exceed length of 30 mm. The
male is yellow, with two round black spots; the chest is dark brown, with
macular degeneration, and brown on the back and chest. Abdomen red, the
Section 4 to 8 has black spots at the end of each side. Female striped
basic similar to abdominal yellow and spotted.
Sympetrum eroticum has been recorded
from China, Taiwan, Japan, Korea, and Russia.
The nominate subspecies Sympetrum
eroticum eroticum is recorded from northeast China, Japan (including Hokkaido,
Honshu, Kyushu, Shikoku and the Ryukyus), and Korea. Needham (1930) described
the synonym Sympetrum ignotum from 'Weisohn, Manchuria'. Hua (2000) records
S. ignotum from Jiangxi, northeast China and Zhejiang, but the records
from Jiangxi and Zheijiang probably refer to the subspecies Sympetrum eroticum
ardens (McLachlan). Zhang and Zhang (12006) record S. eroticum (as S. ignotum)
from Shaanxi. Kosterin and Malikova (2007) record S. e. eroticum from southern,
The subspecies Sympetrum eroticum
ardens (MacLachlan, 1894) is widespread in Tawian and is known from southern
China, including Fujian, Jiangsu, and Sichuan. Wilson (1999) recorded S.
e. ardens from Guangdong. Hua's (2000) records of S. e. eroticum from Fujian,
Guangxi, Guizhou, Henan, Hubei, Hunan, Jiangxi, Sichuan and Yunnan relate
to the subspecies S. e. ardens. The two subspecies are not clearly differentiated,
apart from minor size differences although they overlap in distribution.
Sympetrum eroticum is common and
widespread throughout Japan and Korea and has been recorded from China,
Taiwan and southern far-eastern Russia. The species occupies a range of
habitats and it is not under any serious threat at present. It is classified
as Least Concern (LC) on the IUCN Red List.
