    Found these on a pillow that was under my bed . They are more like skins but just the oval part...

    I don't have any bites or anything. Just paranoia from an outbreak at work. Thanks.

    Not bed bug related in my purely non-expert opinion. Keep checking back for a pro to tell you what they are.

    Not bedbug related. Wait for Lou, but it's some kind of pupae.

    In this bag you have an adult fly and a few fly pupae cases.

    When the maggot has fed and grown sufficiently it creates this pupal case. It then emerges as an adult fly when fully developed as a result of metamorphosis.

    The adult fly is there. It is a species of Calliphoridae, the blue or green bottle flies, though not all species are metallic in coloration. The cases are actually called puparia (singular, puparium) and not pupal cases. The 3rd instar larva creates the puparium with its skin that becomes sclerotized and forms the characteristic bullet-shaped object. The actual developing pupa is inside this case. Adult structures can be seen developing on it as is the case with other insect pupa. The head area sclerite pops open as the adult fly pushes its way out with the help of a structure on the front of its head called the ptilinum, an eversible, fluid-filled sac. When its use is finished, the fluid is withdrawn, the sac pulls in, and all that is left is the upside down U-shaped frontal suture. If you find recently emerged muscoid flies, the head is a little swelled and you can see the sac in motion since it this process isn't instantaneous.
