The phylogenetic tree figure shows genera of moths which mat

The phylogenetic tree figure shows genera of moths which mate on a particular species of flower. However, not all moths lay eggs in a flower. On the tree, each origin of “egg laying in flower” is marked with an open circle. The loss of this trait is marked with a rectangle. Note that the ancestral moth did not lay eggs in a flower.

(a) Name the genera of moths which lay eggs in the flower of a plant.

(b) Which genus is most closely related to the ancestral moth? Also, draw a pointer to the node which shows the ancestor of the ancestral moth and its most closely related genus.

c) Name the genera of moths which do not lay eggs in the flower of a plant.
