Large Milkweed Bug

Oncopeltus fasciatus


Orange and black bug with forward-pointing triangles anteriorly and orange backward-pointing triangles posteriorly, separated by a black band in the middle.


Spotted on milkweed in a meadow.


Oncopeltus fasciatus is a model organism, and is often reared for laboratory experiments. These insects are very easy to rear and handle, have a short developmental time, and high fecundity. When I was in graduate school, I reared these insects and helped conduct experiments to investigate the potential for nontarget effects of entomopathogenic fungi used in the biological control of ticks.
