Extraordinary corn disease

For your information, corn is monoecious plant. Means they have two seperate male and female flower in one single plant. Take a look at the image below.
(Corn gall) (male flower)
This is male flower of corn. They grew at the top of the plant and supposed to produce pollen which would dropped into the female flower (pollination) then corn is produced. But this male flower produced corn grain!! It was weird.. wasn't it?

I cannot explain scientifically why the grains grew on the male flower. I did some research it might caused by an insect named gall midge. I did not know this for sure, the insect injected some chemical substance into the plant part (in this case the male flower) then the galls were formed. But, if it was really the gall midge there must be a larvae in each galls. When I pinched the galls with my finger there was nothing in there. It was fully developed corn grain. Just like in the female flower (where it supposed to be).
