Insects by Order



Nowadays with gene sequencing providing new insights into how living things are related, many traditional concepts are changing, including among the insects. The following is a list of insect orders according to the NCBI Taxonomy Database, as of September, 2010. Note how there are newly recognized orders such as the "Heelwalker Order" plus nowadays cockroaches, mantids and more have their own orders.  Probably these concepts will change more.
