What kind of bugs are they, and do they pose a threat to milkweed plants or caterpillars?
Answer: Milkweed bugs
Lyle Buss, University of Florida entomologist, said that these bugs in the photo are indeed milkweed bugs, a type of seed bug (family Lygaeidae). They prefer to feed on seeds of the milkweed plants, which is probably why they were given that name. Furthermore, milkweed bugs like to spend most of their time on the pods of the milkweed plants.
The bugs featured in the photo are young nymphs, which make them a bit more difficult to confirm their identity. Oncopeltus fasciatus is the most common species in Florida, but there are several other species of Oncopeltus in Florida as well. As a side note, Buss said their bright orange color serve to warn potential predators that they are toxic to eat.
