Life Cycle of Red-flanked scymnus
Egg The egg stage is where the life cycle of red-flanked scymnus begins. These eggs are usually laid in clusters and are oval-shaped. Colors may vary, but typically they're yellowish or pale, offering camouflage. Very small in size, the eggs serve as the developmental space for the embryo.
Larva Upon hatching, red-flanked scymnus enters the larval stage. This is a period of rapid growth, characterized by a worm-like appearance. The larval red-flanked scymnus has a voracious appetite, mostly for aphids if available, and molts several times as it outgrows its exoskeleton, increasing substantially in size with each molt.
Pupal During the pupal stage, red-flanked scymnus undergoes transformation inside a pupa. Generally attached to a leaf or similar structure, the pupa may display colors that blend with the surroundings. The immature insect inside is reorganizing its body structure significantly, developing wings and adult features.
Adult Emerging from the pupa, the adult red-flanked scymnus's development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction. Typically, the adult red-flanked scymnus will display bright colors as a warning or for mating purposes.

How Can You Attract Red-flanked scymnus
Since red-flanked scymnus feed on pests like aphids, using these pests or a synthetic version of their pheromones could serve as trap food.
Rectangle
Habitat Preferences of Red-flanked scymnus Through Different Life Stages
The eggs of red-flanked scymnus are typically found on the underside of leaves, where the insect lays them in clusters near aphid colonies, their primary food source. During the larval stage, red-flanked scymnus inhabit similar environments as they voraciously feed on aphids. Pupae usually attach to the same leaves or nearby stems, camouflaging within the foliage. To seek out these stages, one would meticulously inspect the leaves and stems of plants infested with aphids. Adult red-flanked scymnus are more mobile and can be found on a variety of plants, as they continue to prey on aphids. Searching for adults involves scanning various plants, especially where aphid populations are high.
Rectangle
When is the Best Time to Observe Red-flanked scymnus
Late spring to early fall is often the most suitable time to find red-flanked scymnus as this is when their prey is typically most abundant.
Rectangle
What is the Best Weather to Observe Red-flanked scymnus
Warm, sunny, and dry conditions are generally more suitable for finding red-flanked scymnus as these are the conditions in which their prey is active and abundant.
Rectangle
How and Where Can You Find Red-flanked scymnus at Different Life Stages
Egg Look for red-flanked scymnus eggs on the underside of leaves, especially where aphids are present. Use a magnifying glass as the eggs are often tiny and can be yellow, orange or a similar color to the leaf.
Larva Search for red-flanked scymnus larvae on plants infested with aphids, as the larvae are voracious predators of these pests. They can be distinguished from other larvae by their elongated bodies and distinct color patterns.
Pupal Red-flanked scymnus pupae can be found attached to leaves or other structures near aphid colonies. They are often camouflaged, so inspect the areas carefully where aphid populations are high.
Adult Adult red-flanked scymnus can be found on various plants, especially those with high aphid populations. Look for them on the tops of leaves, stems, or flowers during warm parts of the day. They may also be attracted to yellow or other bright colored traps.
