Lots of info on there. I joined and they sent me a pack including some seeds for plants that the bumblebee loves. Am waiting for a bumblebee day nearby so I can go.
I wrote this little rhyme in 1998
BUMBLEE BEE!
My name is Bumblee Bee, I'm as happy as can be,
Bumbling around, off the ground, with a heart that's full of glee!
I fly to a flower, tall as a tower, and take some pollen with me,
No shops to buy from, banks to borrow from, everything here is free!
My name is Bumblee Bee, I'm as happy as can be,
My body is squat, it's short and fat; Do I care? Not me!
According to laws it shouldn't be, that I in fact am a flying bee,
I can, you see, get off the ground, with a heart that is full of glee!
My name is Bumblee Bee, I'm as happy as can be,
Warm is the sun, I'm full of fun, a cheery bumbling bee!
I buzz and bumble, collect and return to my hive not far away,
Bumbling around, come what may, and never a dollar in pay!
My name is Bumblee Bee, I'm as happy as can be,
I'm not in a hurry, why should I worry, I'm flying as you can see!
Next time you see me bumbling free, be happy like me a bumbling bee,
Defying the laws that shouldn't be, to be in fact a bumblebee!
Bumblee (1998)
