Red-eyed damselfly (Erythromma najas)

 Damselfly 

14 June 2023 Park 

This species is quite a large and robust damselfly, with distinctive 'bug-eyed' look. Adult males have blood-red eyes and tend to rest on floating vegetation. They are very territorial and chase off any other encroaching male. When newly emerged they have nearly all black bodies and dark eyes, but their larger size helps to distinguish them from other species. Immature males and females are generally yellow and black.
