Here's a good one!  Today I read that the collective noun for ladybugs is 'a loveliness.'  A loveliness of ladybugs.  I like it.  I even dress up in a ladybug costume for Halloween, and feel quite lovely.  
 

Don't tell Henry.  He hates them.  They invade his house like there's no tomorrow.  We still visit on Halloween just for a tease.
 

Harlequin Ladybugs were intentionally released in 1979 in the US as biological warfare to control the population of aphids, corn borers, and other herbivores (insects who feed on garden plants.)  They have since become an invasive species, causing a whole new set of problems.  Just ask Henry.  
 

Anyway, I thought it was interesting and hoped you would too.  
 

HAPPY GARDENING!!!!
