I am walking in the garden and see something, it never moved. I took my phone and took some shots of the model that showed her divine beauty. I took five closer shoots, and still, it didn't move. I tried to touch it, and it flew away.
This will be my first entomology blog, and entomology is the study of insects. But in my field of agriculture, we don't just look by the name insects. Also, we do look if this insect was a pest or beneficial; also, we need to evaluate the characteristics of the insect, morphology, and all the aspects in between. For my first subject, let's talk about the dragon in the insect world.
Also comes the time of our field research in the insects subject where we need to catch those insects and look for their part, list the population density, and many more. Taking up an Agriculture related course was cool.
Why are they called dragonflies?
A fascinating organism, yet they are not and never related to dragons; dragonfly is predatory insects which happened they catch other small insects such as ants, houseflies, mosquitoes, and even smaller insect of their kind. Some people don't recognize the dragonfly and the damselfly. The dragonfly that showed in the photo and the damselfly was the one we thought was a minor or baby dragonfly, the colorfully red or blue that happened to be the smaller and thinner side of the dragonfly. Still, the catch is that they are not baby dragonflies. They are another species of insect under the same category as the dragonfly. We called them Odonata.
Odonata is an order of Insecta, "Odon," which means teeth. Odonata is a predatory insect, the natural predator of mosquitoes, so when you see some don't catch or play with their wings, they play a vital thing, especially in the control of dengue outbreaks and some insects that hold a virus.
Dragonfly has many variations in size and color, and some might see the green pigment of a large and small one, others had seen the colorful yellow and red both medium length and a small one, others dragonfly would remind their childhood as they tried to catch under the heat of the sun.
Many memories remind us of these fascinating insects, but let's look at some scientific side of these fascinating insects.
What makes the dragonfly becomes an insect?
In entomology, we only be called insect when it has the following, first have three pairs of legs, and dragonfly has that one, next have distinct body region (Head, Thorax, and Abdomen), they have one pair of antennae, dragonfly have one pair of the part. Let's try to explain them in the matter of understanding in the simplest ways possible, and if there is something you cannot, don't be hesitant to ask in the comment. I will love to have a conversation in the comment section.
Pairs of Legs: Dragonflies have three pairs of them.
Have you not been curious to catch one and feel what was in the legs, a spiky that could be glued to your skin? Dragonflies have raptorial legs, which will easily catch their prey using legs designed for grasping—a kind and typical for predatory insects.
Dragonflies have the whole region of the head, thorax, and abdomen. The photo shows where it is located, the head with the eyes and mouth. The abdomen is where the secretion starts and ends. This makes the dragonfly and damselfly the formation of their head, thorax, and abdomens. They could balance it easily to fly fast even though their stomachs were full.
Now take a look at the antennae of the insect. The formation is called Setaceous, or bristle-like segments, the same as green leafhoppers. They use this antenna to detect prey, their food, or even predators that look larger than them. Like other insects, they use the antenna to hear the sound and try to recognize it as warming in danger yet to come.
Dragonfly Heads.
Dragonfly heads were classified as Hypognathous heads, which meant that the head part was perfect and the right angel or it displays. Unlike other insects that mouth part was hiding or underneath their legs, the head was designed with their eye, and dragonfly eyes were classified as compound or like humans have the pairs of it. We don't say insect mouth, we called it mandibles in entomology terminologies, so if you somehow encountered the word "mandibles," it also meant the insect mouth part, just some trivia.
About the wings of the dragonfly, its wing formation of Membranous type wings is transparent and attached to the insect's thorax.
It sounds cool to study insects. They have these names and variations that make them unique to other insects. Remember the key points, Dragonflies belong to an order of Odonata, meaning they are predatory insects.
The Dragon Fly How Its Become Beneficial?
In agriculture and the creation of Integrated Pest Management (IPM), we wanted to control and minimize insecticide use due to the global effects of the chemicals in land and water. As to alternatives, one of the best sides is the 'natural enemy' or predatory insect. Also, in the Philippines, as the rainy season begins, the number of cases of dengue outbreaks comes to the threshold level. One of the predators of mosquitos is the damselfly and dragonfly.
They play a vital role in the ecosystem. Controlling and monitoring the population of pests and other harmful insects to humans.
Now you learn some information about the dragonfly, yet not totally a dragon. Next following we could also look for other insects that are normally present in the backyards of your gardens and home.
