The animal kingdom is vast, especially the insect world. Did you know there are over 900 species worldwide? That's incredible! Many of them are very different from each other: some insects can fly, others can't; some are excellent burrowers, while others are great climbers. The diets of these tiny creatures also vary greatly. Even so, many species look very similar. This is the case with damselflies and dragonflies, which are often confused because of their very similar appearance. Would you be able to tell them apart?
If not, I recommend you keep reading. In this article, we'll explain what damselflies are and what the main differences are between them and dragonflies. After learning this, you'll never confuse them again! We'll also discuss how this species reproduces, as it's a very striking and curious process that requires a lot of balance from those involved. They're quite the acrobats!
What are damselflies?
Let's begin by discussing what damselflies are. Despite what their name might suggest, they are neither horses nor seahorses. Damselflies are actually insects, specifically a suborder belonging to the order Odonata . The scientific name for these little creatures is Zygoptera. These flying insects have impressive colors and, due to their physical resemblance, are often confused with dragonflies. However, if we know both types of insects, it's very easy to tell them apart. For this reason, we will discuss the differences between the two species later on.
Since damselflies don't have the same strong and developed musculature as, for example, dragonflies, they tend to be less active. Therefore, they usually hunt stationary prey, that is, prey that is perched in one place. Damselflies begin to develop their predatory instincts as larvae. During this stage, they devour the larvae of other small insects, such as mosquitoes or flies. It should be noted that there are some larger species that live in the tropics that can even feed on spiders while still larval.
What is the difference between a dragonfly and a damselfly?
Now that we know a little more about damselflies, let's see how they differ from dragonflies. First, it's worth noting that dragonflies are much larger and more active, which is why we tend to see them more often. Damselflies, on the other hand, fly less and are somewhat more fragile.
Aside from size and activity, there are other differences between the two species, such as their wings. What they have in common in this respect is that they have two pairs, one forewing and one hindwing. However, in damselflies, both pairs of wings are the same size. Furthermore, when they are not flying, they fold them against their abdomen. In contrast, dragonfly wings are not the same size; the hindwings are larger and have very strong muscles to facilitate flight. Therefore, this species is able to travel much faster and farther. However, they do not have the ability to fold their wings when they land.
Although both species have large, prominent compound eyes, these eyes are different. Dragonflies' eyes are closer together and somewhat larger, while damselflies' eyes are farther apart and smaller. Their body size also differs significantly. Damselflies are more slender and cylindrical compared to dragonflies, which are larger and more robust. Furthermore, dragonflies tend to venture far from the water, while dragonflies always stay close. Their hunting behavior also differs. Dragonflies hunt prey in flight, while damselflies typically hunt stationary prey.
Damselflies: Mating
One curious aspect of damselflies is their method of reproduction. The mating of these insects is a truly remarkable balancing act. The male possesses two upper appendages in the anal region, known as cerci. With these, the male grasps the female's head from behind, creating a kind of tandem. In this position, they fly from one place to another. It is very easy to distinguish the male from the female in this posture, as the female's abdomen is usually thicker.
Male damselflies typically have a genital pore at the end of their abdomen, a characteristic they share with many other types of insects . However, they also have another genital pore at the front, roughly halfway down their body. This is where their sperm-injecting organ, or penis, is located. Therefore, before mating with the female, the male must first transfer the sperm capsule from the rear pore to the front one.
During mating, the male curls his abdomen so that the female's genital pore, located at the end of her body, can align with his. During this process, the female is lifted twice by the male and eventually clings to his own abdomen. This courtship dance typically takes place near ponds or other bodies of water with prominent trees. Egg-laying usually occurs on the bark of trees and aquatic plants, such as willows.
A priori it may seem like a very strange and uncomfortable way to reproduce, but we must not forget that the bodies of these animals are prepared for it. Nature is intelligent and knows how to achieve adaptations that are evolutionarily advantageous. I hope this information about damselfishes has been interesting for you!
