Introduction. Male dragonflies show two forms of mate-guarding behaviour: (1) tandem guarding, in which the male holds the female by the head during oviposition, and (2) non-contact guarding, in which the male hovers or perches above the female during oviposition and chases away intruding males.
Keywords. dragonfly, Sympetrum obtrusum, mate-guarding
