Aphid????

Aphid.
" Mom, we learned about Aphids in school today." Words out of a kindergartner's mouth.
" A what? " I proclaim.
" Yep, butterflies eat Aphids mom." Says my little man.
" He is learning about things that I am learning in school." explains Brit. ( who is in the 7th grade)

Now I know.
Boy I feel stupid.
