Cephalaeschna klotsae, also known as “Yellow-spotted Dusk-hawker” is a dragonfly species in the family Aeshindae described by odonatologist Syoziro Asahina in 1982. It is an endemic species of China, specifically distribute in Hubei, Guangdong, Hongkong, Zhejiang, Fujian and Anhui.[1][2].
Description
[edit]The body length of this dragonfly species is around 70~77 mm, the abdomen length is 54~61 mm and the length of their hindwings is around 46~49 mm [1]. This species does not have significant sexual dimorphism, they have olive green colored compound eyes with dark brownish faces, their legs are black, thorax is black with 2 pairs of light green strips on each side and 1 pair on the front, wings are transparent, abdomen is black with parallel light green strip-like spots on 1st~8th segment; color of females is lighter and their ovipositors are comparatively less developed [1]. The naiad has inverted trapezoidal head with pumped out compound eyes [2].
Biology
[edit]The species dwelling in elevation around 300~2000 in mountains; Cephalaeschna klotsae 's naiads live in a semi-aquatic environment, that means they can move, capture prey, and molt on land, mainly in mosses and ferns surround little waterfalls and seepage stone walls and naiads are highly camouflaged [1][3]. The adults are diurnal hunters that are active near the breeding site, preying on small insects, the species' flight season is from May to October [3].
Natural history
[edit]The phylogyny of genus Cephalaechna is poorly studied [4]. However, from morphology perspective, the naiad of Cephalaechna is very similar to genus Planaeschna [5]. An article written in 2002 also suggests that Cephalaechna is the sister group of genus Caliaeschna [6]
