Ladybugs - Description
Hippodamia convergens · How to Say It: hip-oh-DAY-mee-uh kun-VER-jenz
Native ladybugs are general predators effective for aphid control.
If you are struggling with aphids, mealybugs, or other soft-bodied pests taking over your garden, our pre-fed ladybugs are a natural way to bring the problem under control. Hippodamia convergens, commonly called the convergent lady beetle, is a North American native predator best known for its appetite for aphids and other soft-bodied pests.
Ladybugs are generalist predators that feed primarily on aphids but will also consume a variety of other small insects, insect eggs, larvae, and mites. When pest populations are low, adult ladybugs will supplement their diet with pollen and nectar from flowers. Every batch is pre-fed before shipping to help them settle in after release. They are a great option for gardeners moving toward more sustainable pest control.
What Ladybugs Are
Native ladybugs have the classic dome-shaped body of the Coccinellidae family, typically 5–8mm long, with red-to-orange wing covers and black spots, though spot count and color vary more than people expect. Some individuals carry a dozen spots, others just a few, and some have no spots at all. Spot pattern alone isn't a reliable way to identify a beneficial lady beetle versus a look-alike. The native convergent lady beetle has two thin white lines on its head that "converge" toward the center of the shield-like plate behind the head.

How Ladybugs Work
Adults home in on aphid colonies, where they feed and lay eggs under the right conditions. The larvae are the most voracious feeding stage and are responsible for most of the aphid suppression. Adults continue feeding for weeks given adequate food and water, extending aphid control. When threatened, ladybugs release a bitter-tasting, foul-smelling compound from their leg joints that deters birds and other predators from eating them.
Life Cycle & Identification
The full life cycle from egg, larva, pupa, to adult takes roughly 2–3 weeks under good conditions. Ladybug larvae look nothing like the adults. They're elongated, spiny, and often gray or black with orange markings, which surprises a lot of first-time gardeners expecting a mini version of the dome-shaped adult. After pupation, adult beetles continue feeding for several weeks and can lay eggs among aphid colonies.
When to Use Ladybugs
Ladybugs work well both preventively and reactively:
- Preventively: Release when aphids are beginning to appear, rather than waiting for a severe infestation.
- Reactively: Release at the first sign of an active infestation to knock populations back quickly.
Pairing and Compatibility
Works well alongside other natural predators to provide more complete aphid control across the growing area.
- Parasitoid wasps like A. colemani, A. ervi, and A. abdominalis can help control aphids by laying eggs inside the aphid and turning them into mummies from which their offspring will hatch.
- Green lacewing larvae (Chrysoperla rufilabris) are referred to as "aphid lions" and are highly mobile generalist predators that attack aphids and other soft-bodied prey.
