One word for a ladybird (the red insect with black spots, "ladybug" being the American name) is a "πασχαλίτσα".  Apparently, it's also called a "παπαδίτσα".  I've no proof of this, but knowing the two dictionaries I have here, I suspect the former is an older, and the latter a more modern term.

Pronunciation is: "πασχαλίτσα" = paschaleetsa (the "ch" as in Welsh or Scots Gaelic); "παπαδίτσα" = papatheetsa.  In each case, the stress is on the "ee" sound.

I've found no suggestion that either has a rude or abusive meaning, but many dictionaries skirt over that anyway, so it's still a possibility.

I've not found anything that corresponds directly with "pakalitsa".
