Seven-spotted Lady Beetle Coccinella septempunctata

Before pesticides took over, farmers and gardeners already knew the secret: these beetles are voracious aphid-hunters. A single seven-spot can demolish hundreds of aphids in its lifetime, which is why it's been shipped worldwide as nature's pest control. What makes them so good at the job? They adapt to almost any habitat on the planet—forests, gardens, grasslands, crops—making them one of the most successful predatory beetles ever.

With roughly 5,000 ladybird species out there, this European native has become the celebrity of the group, instantly recognizable by those seven black spots on its crimson shell.
