The Travelling Insects

Change is a very important factor for all living things out there, right from humans to animals to birds all living species travel through various distances because of several reasons. Similarly, insects are the of living species that travel to places far away and cover several miles of distances due to various factors involved. The insects that migrate the most from one region to another are the green darners. There is this annual cycle that describes their migrating behavior; the migration of the green darners depends on the generations of the insects. There are a total of two generations of green darners that form the annual migrating cycle, the first one comprises of two generations of migratory generation, and the second one comprises of the non migratory generations. So, their migration cycle has a pattern that is followed every year. The first generation makes the first spell of rounds from the southern to the northern range limits; here they lay eggs and then die. This prevents the species from getting extinct as the eggs prevent the breed and the new generations to survive. Then the pattern is continued by the second generation that is born from the eggs laid and they travel back to the southern range, from where their first generations had started the journey. Then the last round of spell starts as the resident generation of the green darners emerges, however they tend to reproduce locally and give rise to the population at the set location. This generation then again starts the annual cycle the next year where they travel to the northern range the next year. The same cycle continues every year and hence these insects reproduce, die, lay eggs and make sure the specie remains alive through migrating to and fro across the northern and southern range limits.

Comparing these ‘travelling’ insects to humans, one can deduce that migrating make these insects spread over several locations and they leave their foot prints on these location extending their reach all across the globe. A very interesting factor to note is that these insects migrate and carry out their annual cycle according to the seasons yearly. They make their first round of spell in the spring season of every year as in spring the insects with the southern origins arrive at the northern locations beforehand the species that have the origins from the mid latitudes. Similarly they thirds round of spells is most suitable in the autumn season. This happens when the individual insects are trapped in the southern part of the region. This migration has various positive effects most importantly the insect species become immune to all kinds of negative consequences, they learn to take advantage of the warm surface waters that helps them travel easily over the water bodies and this can cause them to travel immense long distances and this can cause the insect species to spread all over the world, making the insects a specie common all across the globe. This unique strategy and the cycle of nature make great revelations about how things work apart from the human and animal natural cycle. The migration of animals can be because of several reasons be it ecological and emigrational, however the migration has a very positive impact on humans, animals and insects.
