Dragonfly vs. wasp - Dec 11

A question was asked – who would win in a fight, a dragonfly or a wasp? Here is the short answer – it is a trick question!

As a starting point, the two insects are built quite differently. Both, of course, have the same insect body plan: an abdomen, a thorax with 4 wings and 6 legs, and a head with eyes, jaws, antennae, and whatever else insects have there. Beyond this generalization, however, a dragonfly and a wasp are built differently.

A dragonfly is built for speed. It is the cheetah of the insect world. Unlike the tall cat, however, a dragonfly has endurance as well as speed, as it spends all of its adult life flying around, looking for food and mates. Dragonflies are not territorial… unlike their damselfly cousins, which are: males of those insects have a perch/an established territory, and they keep each other out of it, but damselflies are not as good fliers as dragonflies are. Moreover, we are talking primarily about dragonflies here.

Wasps are more territorial, meanwhile. There are two main wasp types: the solitary and the social, and here we are talking about the social species, such as the paper wasp and the hornet. They are as carnivorous as any dragonfly is, but are also social, while dragonflies are not.

What is more important, though, is that while dragonflies are built for speed, as the cheetahs are, the wasps and hornets are built for strength instead, (as the lions and tigers are). Moreover, not unlike the lions, wasps are known to cooperate with each other, though along different lines than those of the vertebrate lions. To wit: while wasp nests are more numerous than the lion prides, the bonds between the lions are stronger, because, well, the lions live longer – for years, while in temperate climates wasps die at the end of fall/beginning of winter – only the wasp queens survive. (I.e. the wasp analogues of the bee queens).

…The dragonflies, it can be argued, do not fair much different: they also die in winter, and only their eggs, or larvae, survive the winter. Unlike the wasps, however, they do not have a pupa stage: when they are ready to transition from water to air, they crawl out of the water onto a tall cattail or reed, and burst from their back – literally: the skin on their backs bursts, and the adult dragonfly crawls out of its’ last larval skin. Alien xenomorphs, top that.

Getting back to our face-off, the dragonfly can fly, well, rings around a bulkier wasp, but unless it is really bigger than the wasp is, it will not tackle the wasp, and we are talking literal tackling here.

A wasp hunts with its’ sting, (in a manner of speaking): when a wasp finds its’ prey, (a spider, a caterpillar, a honeybee – it is different with different wasp species), it jumps onto its’ prey and paralyses’ it with the stinger. Then the wasp takes its’ prey to its’ nest, where it either feeds the prey to the larva, (as the social wasps do), or puts it into a storage, and lays its egg, so that the larva would eat the spider/caterpillar/etc. later, (as the solitary wasps do).

Meanwhile, dragonflies have no stingers – they just rush at their prey, seize it with their legs and eat it. The legs of dragonflies are hairy and spiky, useless for working, just fine for perching, and when the dragonflies fold them, their legs form a fine net/basket for catching insects such as mosquitoes and butterflies, but against powerful wasps – not so much. Venomous stingers aside, wasps and bees are just too heavy and strong for dragonflies, and the dragonflies do not mess with them.

Robber flies sometimes do. Despite being, well, flies, and as such, related to houseflies and mosquitoes, the robber flies live more like the dragonflies, being active hunters, especially as adults. A scientist once put a robber fly against a bumblebee. For a while, the former seemed to be gaining the upper hand, until the bumblebee unleashed its stinger and went on the counterattack. The robber fly quickly played possum and the bumblebee got away. Considering that the robber flies have a venomous bite of their own, and the dragonflies do not have it, the fight between a dragonfly and a bumblebee – or a wasp, for that matter – would have been over even quicker.

Therefore, getting back to the initial question: who would win, the dragonfly, or the wasp, the answer is the wasp. However, since a dragonfly would never tackle it, this answer is theoretical overall.
