Title: How are insects classified?
Post by: yacubovvs on 18/07/2018 13:32:08
Hello everyone!
I always see many insects in nature, but do not know who they are.
I decided to make a data base of any known insects to help everybody to identify insect by answers on simple questions (length, color, number of legs, number of wings and etc).

If you know any material about insects classifier or about insects identify please send a link. Or maybe you can recommend me a person to contact for help.

Thank you.

I classify insects as either "likely to bite me" or "not likely to bite me".
Other classifications are also used.

I can tell you that insects will always have six legs (unless they are injured or mutated). Likewise, insects always either have no wings, two wings or four wings.

I would suggest a "top-down" method that starts by identifying which order the insect is in, which is pretty easy in most cases. Insect orders include coleoptera (beetles), hymenoptera (bees, wasps and ants), lepidoptera (butterflies and moths), diptera (flies), orthoptera (grasshoppers and crickets) and many others. Once you figure out what makes each of these orders unique, you can work that into your programming to start on the next stage: the characteristics of each family within each order. Then the characteristics of each genus within each family, and finally the characteristics of each species within each genus. Fair warning though, that would take a lot of work! There are almost 1 million species of insect known. You might be better off stopping at the family level instead of going all the way down to species.

any material about insects classifier
Traditionally, insects (and other species) were classified by their shape, and sometimes by how they grow.
For very similar insects, experts use a microscope and examine their reproductive organs. Apparently this is more distinctive than color or wing shape.

Today, the availability of (relatively) cheap genome sequencing means that a computer program compares an insect's genome with the genome of all other insects - and sometimes this comes up with a different grouping and classification than you would obtain through more traditional microscope methods.

But for an amateur today, classifying insects by body shape with a magnifying glass and microscope will be more practical than gene sequencing.

But this priority may be reversed in 20 years: gene sequencing is said to be doubling in cost-effectiveness about every 9 months; if current trends persist, 20 years represents 100 million times cheaper. than today..

I would recommend my strategy:
Firstly you should split all insects into two categories:
Flying and not-flying insects.
After, i think, it would be useful to define dangerous and not dangerous.
Category "Dangerous" should be splitted into "Deathly Dangerous" and "Not Deathly Dangerous".
And there should be field "Can be met in your house".
So we can add pictures and know our enemies in their faces.
Don't know what about you but I want to know which one can kill me and how to get rid of it.
It is pretty interesting so in case you would decide to use my idea notify my please
