The Twice-Stabbed Lady Beetle is an excellent friend to gardeners thanks to its ability to hunt and consume plant-harming bugs at an astonishing rate.
The twin red spots on the shiny black elytra of the Twice-Stabbed Lady Beetle help in identifying it. A narrow ridge, or lip, extends from the bottom edge of the elytra. It is not a delicate insect; this beetle sports strong mouth parts capable of chewing through the tough armor-like exoskeletons of many other insects. The beetle naturally and organically rids plants of pests that may ruin leaves and fruit, or possibly kill the plant. They prey on scale and other things that can infect plants with fungi or viruses. This makes it a tremendous ally to gardeners and growers. Females place their fertilized eggs in the empty carcasses of scale insects for protection.
Females are able to emit a noxious substance from their legs and they have a reputation for tasting foul. These two defense mechanisms reduce the likelihood of predation by birds and other small animals. Gardeners should make a point to recognize this Lady Beetle and not mistake it for the obnoxious Asian Multi-colored Lady Beetle, the multi-spotted, stinky species known for moving into homes and buildings for shelter.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Antennae: Beetles have a pair of antennae on the head used as sensors.
Head: The head is home to the insect's eyes, antennae, and mandibles (jaws).
Thorax: Holds the three pairs of legs as well as vital internal organs.
Elytron: One of two wing cases on a Beetle that protects its wings (plural: elytra).
Wings: Appendages used for flying and kept under the elytra until needed.
