Appearance

The species is a small damselfly, 35 millimetres (1.4 in) long, predominantly black with iridescent blue markings. The male resembles blue-tailed damselflies (Ischnura species) but is distinguished by its large, spaced eyes that are a deep red. It is very similar to the small red-eyed damselfly (Erythromma viridulum).

Behaviour

Males typically spend much of their time perched on the leaves of floating vegetation such as water lilies or mats of algae.

gollark: I failed to come up with a non-politically-charged example so I'll just use a horribly politically charged one: people arguing over statements like "abortion is murder" is pointless, as you're basically just arguing over whether you get to associate it with bad things or not, instead of getting to the actual underlying questions about, say, rights of unborn babies.
gollark: It doesn't help your argument, or help people more accurately think about the actions, or whatever.
gollark: I am talking meta-level here; I'm not saying "culling is unhelpful" but "it doesn't actually help anything to try and shove things into the culling box".
gollark: It might not be *technically wrong* by a strict definition to say that trying to improve health standards and whatever to reduce population growth is culling, but it's not... helpful? As in, it doesn't really matter whether the relevant actions fit into [bad and emotionally charged category], but whether they're actually bad.
gollark: "Culling" is generally meant to mean something more like actively going out and killing people.
