Hi, there, Joybell, what a fun project!

I have a few insect songs; one is

What do caterpillars do?
Nothing much but chew and chew!
What do caterpillars know?
Nothing much but how to grow!
They just eat what by and by will make them be a butterfly,
But that is more than I can do,
However much I chew and chew!

I could probably record it or make a midi and send it along!

I also have an odd song collected or written by Bartok, about a cricket and a spider getting married. It mentions gnats, fleas, cockroaches- and ends with the line,
"Creepy, crawly, mad fling!"

Either of these would be good with your 5-8 year olds.

If you'd like either song, PM me and I'll get them to you somehow!

Allison
