Thank you for your question, Andrea.  The photo is too unclear to be certain.  Are you able to place it on a sheet of white paper, and get it clearly in focus?  I suspect that it is a spotted lady beetle, which is attracted by aphids which suck on the undersides of leaves.  If you can't get a better photo, you can take the insect to the Washington County Extension office for id.  https://extension.oregonstate.edu/washington

Good luck!

Thank you, Andrea.  I have researched without success; I've tried to find another expert, one with insect expertise, without success; and the person who assigned this to me is on vacation.  Argh!  I'll keep trying.  Sorry for the delay.

Hi Andrea,

Nice photos!
Those will actually do no harm to your hibiscus and may even help them.
That is a pupa and a cast pupal exoskeleton (after the adult emerged) of a ladybug (Family: Coccinellidae). Since ladybug larvae and adults eat aphids and other soft-bodied insects that can be plant pest, they are considered beneficial insects.

Does your hibiscus plant have aphids or has it had aphids recently? Or perhaps does an adjacent plant have aphids? If so, that could explain why you have a number of ladybug pupae on your plant.

Best wishes!

Hi Bill,
