Sympetrum eroticum

Four-tipped darter

Both sexes carry two small black eyebrow-shaped marks on the face, the feature that gives this dragonfly its Japanese and English names.

WhereRice paddies, marshes and grassy wetlands
Size30 to 43 mm body length
WhenJuly to November

Males redden across the abdomen and wing bases as they mature, while females usually stay yellowish brown, though some also turn red. A pair of small black eyebrow-like spots above the face separates this species from other red dragonflies found nearby.

This species breeds in the shallow, often temporary water of rice paddies, ditches and marshes, where the nymphs develop before the adults disperse to grassy ground nearby. It is also less wary than many dragonflies, often letting a person approach closely enough to see the facial marks clearly.
