Large Milkweed Bug Nymphs

Dear Nicole,
Many people plant milkweed because of Monarch Butterflies, but there are a host of insects that depend upon milkweed for survival, including these Large Milkweed Bug nymphs,
Oncopeltus fasciatus.  According to iNaturalist:  “Juvenile O. fasciatus require the seed of milkweed plants for development and growth. Adults can survive on other types of seeds such as: sunflower, watermelon, almond and cashew, as shown in lab populations. Nymphs live in large groups of about 20 individuals on the plant.”  Since they feed on the seeds and not on the plants, they will not damage the milkweed and there will be plenty of leaves for Monarch caterpillars to feed upon.
