Insect field note
A tiny, hungry helper
The Ladybug's Garden Duty
A single ladybug can eat dozens of plant-munching aphids in just one day.
Let's look closer
How can such a small, spotted bug make such a big difference?
adybugs hunt soft-bodied pests like aphids that damage leaves and stems by sucking out the plant's juices, and their small size lets them search every curled leaf and hidden stem for a meal other predators might miss. A ladybug's larva actually eats even more aphids than the adult beetle does, since it needs enormous amounts of food to fuel its own rapid growth before it changes shape. Gardeners often welcome ladybugs on purpose for this reason, since a healthy population of hungry beetles can do the work of a whole bottle of pest spray, without any chemicals at all.

Explorer clue
Check the undersides of garden leaves for tiny yellow eggs or clusters of aphids; a ladybug is often patrolling nearby.
