Dragonfly/1.03.25

Dragonflies are basic fliers. Dragonflies are effective bat, imp and sprite killers (before sprites are too fast). In numbers, they have a chance against a lone wasp (which is slightly superior in stats), and even against the powerful eagle, due to their non zero armor, and their quite high combat score and the consecutive impalements, they can also cause poison, allowing their bites to leave some extra lasting impression.

Plaguelords
There aren't any basic fliers that cause disease, so the Plaguelords had to settle for one that caused poison instead. (I never understood why bats never caused disease.) But their poison is weak and they cost that sacred resource - crystal. It may not seem a lot at first but soon mounts up when you need to build a swarm of them in order to make them actually accomplish something.

Ssrathi
The purpose of the Dragonfly is to inflict Poison upon aerial targets, but the problem here is that the Ssrathi have much better options for doing just that, and at the same tier level, too. However, up untill tier 4 the Ssrathi have limited ways to deal with aerial targets, relying heavily on fire attacks from their Snakepriests. This leaves the Ssrathi unable to fend off early Daemon attacks summoned from enemy Heroes. Although Dragonflies are utterly terrible, they can help out with this one situation - just remember to have a large swarm of them and even back them up with Snakepriests for extra damage, even if it is a small amount due to the Daemon's fire resistance, lest the Daemon will just feed off them and grow even stronger!
