This is not surprising, given that odonates are all aerial predators, and they have always hunted other airborne insects.

The genus " Libellula " is mostly New World, but also has one of the few endangered odonates from Japan : " Libellula angelina ".
19.
Since their diet consists entirely of insects, odonate density is directly proportional to the population of prey, and their abundance indicates the abundance of prey in the examined ecosystem.
20.
This means that in a location such as a lake, if one finds a wide variety of odonates, then a similarly wide variety of plants should also be present.
