What is the point.....?

Question

in a wasp ? I can understand why we have most other insects but the wasp or the flea come to that. I really cant see why we have them.

Answer 1

They aren't here to benefit anyone. They are here to benefit themselves. They evolved to fill a niche and exploit certain resources, and they are doing just that. However, in turn, other animals have evolved to exploit them (via predation, flowers attracting them as pollinators, etc...). No species needs to have a "reason" or "use" to be here. They just ARE here because they found a way to survive.

Answer 2

If you dont know how important wasps are(and every other creature), then you are sadly lacking in knowledge. There is not one living creature on this earth that does not serve an important purpose that it is perfectly suited for.

Excerpts from Wikipedia.... Wasps are critically important in natural biocontrol. Almost every pest insect species has a wasp species that is predator or parasite upon it. Parasitic wasps are also increasingly used in agricultural pest control. http://en.wikipedia.org/wiki/Wasp#Characteristics

A diverse range of wasps lay their eggs on or in the body of an insect host, which is then used as a food for developing wasps. Parasitic wasps take much longer than predators to consume their victims, for if the larvae were to eat too fast they would run out of food before they became adults. Such parasites are very useful in the organic garden, for they are very efficient hunters, always at work searching for pest invaders. As adults they require high energy fuel as they fly from place to place, and feed upon nectar, pollen and sap, therefore planting plenty of flowering plants, particularly buckwheat, umbellifers and composites will encourage their presence.

Three of the most important groups are;

Ichneumon flies: (5-10 mm). Prey mainly on caterpillars of butterflies and moths.
Braconid wasps: Tiny wasps (up to 5 mm) attack caterpillars and a wide range of other insects including greenfly. A common parasite of the cabbage white caterpillar- seen as clusters of sulphur yellow cocoons bursting from collapsed caterpillar skin.
Chalcid wasps: Among the smallest of insects (<3 mm). Parasitize eggs/larvae of greenfly, whitefly, cabbage caterpillars, scale insects and strawberry tortrix moth. http://en.wikipedia.org/wiki/Biocontrol#Parasitic_wasps

Answer 3

We, do not have them. They are the way for wasp or flea genes to replicate. There are many paths that genes use to replicate themselves. Wasps and fleas are but two of them. You need to stop thinking in a teological manner.

Answer 4

they could be here because they were best evolved to find their specific food sources. noone can really tell that though.

Answer 5

there just a part of life
