Life Cycle of Oleander seedbug
Egg The egg stage is the beginning of the oleander seedbug's life cycle. The eggs are often laid in clusters and are typically small and may be colored to blend into the environment. During this stage, embryonic development occurs inside the egg until the nymph emerges.
Nymph Upon hatching, the oleander seedbug enters the nymph stage, resembling miniature adults without fully developed wings. The nymphs undergo multiple molts, growing larger with each stage. Color and size changes are noticeable, but reproductive structures are still immature.
Adult The final molt culminates in the adult stage of oleander seedbug. The wings are fully developed and the exoskeleton hardens with distinctive color patterns. Adults are mobile and focus on feeding and reproduction, eventually seeking mates to continue the life cycle.

Habitat Preferences of Oleander seedbug Through Different Life Stages
The eggs of oleander seedbug are often found on the underside of leaves of Oleander plants, since it is a primary food source. Nymphs generally remain on or near their host plant, exploiting the foliage and stems for sustenance and cover. Adults prefer to inhabit the same Oleander bushes, but can also be found on other nearby shrubs or plants, frequently soaking up the sun to regulate their body temperature. If you're seeking to observe various life stages, you'd scour Oleander plants meticulously, inspecting the undersides of leaves for eggs, looking closely at stems and new growth for nymphs, and examining flowers and leaves where the adults may be resting or feeding.

Are Oleander seedbug harmful to humans?

The long bug does not bite or sting. They have a colorful appearance, used to warn other creatures: "I am poisonous, don't eat me!" Fortunately, the alert color and toxins are prepared for predators. People are only in contact with their body surfaces, only disgusted by the smell of the smelly liquid they secrete, and there is no risk of poisoning.

Agricultural Pests

When oleander seedbug populations are low, minor feeding marks on leaves and stems might be observed, with negligible impact on crop yield. However, severe infestations can lead to significant wilting, yellowing, and death of plants. In large numbers, these pests can cause considerable economic losses and may lead to the increased use of pesticides, with potential environmental and human health implications.
