Entomology Exam!!!

Tomorrow is praUAS for this subject. I must get an A in this subject. It’s must! I am entomology students, that’s embarrasing if i fail in this subject. So, tonight i study hard to mastering this topic. Oh Lord help me...

In this topic, i have to know the characteristic of each Order in the Class Insecta. Wew,..it’s so much for me! But...ok, let’s solve this one by one. First, i made some concept of this topics. I draw the Phylogeny trees of hexapode. So i know the history of the insect evolution. I think it will be easier if i memorize this in sequences from the beginning to the end evolution.

Hexapode is separated into two groups based on it’s mouthparts. The first group is Enthognathus. It is a group which has a mouthparts inside the caput capsule. The Enthognathus group is common as Paraisecta. It has two classes, they are Colembola and Protura. The colembola has 5 segments in it’s abdomen, so that it doesn’t include in Insecta class. The Protura doesn’t have antennae, so it’s not Insecta too.

The second group is Ectognathus. It is a group which has a mouthparts outside the caput capsule. Class Insecta is include in this group. In insecta class, we will find Subclass Pterygota (wings presence) and Apterygota (wings absence). In Pterygota there are Infraclass Neoptera and Paleoptera. Apterygota is consist of 3 orders. They are Order Diplura, Order Archeognatha and Order Thysanura.

Insects which in Infraclass Paleoptera are Order Odonata and Order Ephemeroptera. In other side, Insect from Infraclass Neoptera separated into to division. They are Division Endopetrygota (wings inside the body) and Exopterygota (wings outside the body). Orders which in Division Exopterygota are mostly developed in Paurometabola type. They are Superorder Orthopteroidea and Superorder Hemipteroidea.  Insects in Division Endopterygota mostly are insect which has Holometabola developing type. They are Superorder Neuropteroidea, Superorder Mecopteroidea and Superorder Hymenopteroidea.

The orders of Orthopteroidea are Order Blattidea, Order Mantidea, Order Orthoptera, Order Isoptera, Order Phasmatodea, Order Grylloblatidea, Order Dermaptera, Order Embioptera, Order Zoraptera and Order Plecoptera. The orders of Hemipteroidea are Order Psocoptera, Order Hemiptera, Order Phtyraptera and Order Thysanoptera.

The orders of Neuropteroidea are Order Megaloptera, Order Raphidioptera, Order Neuroptera and Order Coleoptera. In other side, the orders of Mecopteroidea are Order Mecoptera, Order Diptera, Order Siphonaptera, Order Tricoptera and Order Lepidoptera. And the order of Hymenopteroidea is only Order Hymenoptera.

Hopefully i will not forget in exam tomorrow. Wish me luck!
