Sometimes, the origins of insects’ names are pretty inscrutable, but not that of the Seven-spotted Ladybug. Its name does need a little unpacking, though – like the firefly/lightning bug, the ladybug/ladybird is a beetle (alternate name, lady beetle). The Lady in question is the Virgin, to whom the people in the Middle Ages prayed when aphids were devouring their crops, and who is said to have responded by sending this species of aphid-loving beetle.
