The classification is as follow:

1-Class: Insecta

2-Order

3-Family

4-Genus  

5-Species

If two insect species are in the same family they share the same order, but not in reverse mode

Two insect species have the most recent shared common ancestor if they are in the same Family since this group is more inclusive than one defined by the Order  

If an insect species X and other insect species Y are in the same Family,  is more likely that X and Y have the most recent common ancestor compared than the insect species Z that is in a different family
