Ladybugs have emerged. One mystery solved! Here's one of my favorite poems by Joan Walsh Anglund from The Random House Book of Poetry for Children (used with permission from the author):
Ladybug
A small speckled visitor
wearing crimson cape,
brighter than a cherry,
smaller than a grape.
A polka-dotted someone
walking on my wall,
a black-hooded lady
in a scarlet shawl.
