Other butterflies will only lay eggs on specific plants such as the famous Monarch butterfly (Danaus plexippus), which lays eggs on, and whose caterpillars eat only Milkweed plants (Asclepias spp.). The female, after mating with a male, will seek out an appropriate host plant on which to lay her eggs.
The iliac crest is the curved superior border of the ilium, the largest of the three bones that merge to form the os coxa, or hip bone. It is located on the superior and lateral edge of the ilium very close to the surface of the skin in the hip region. When a person places their hands on their hips, it is the skin above the iliac crest that they rest their hands on.
Several important hip, back, and abdominal muscles have their origin at this bone. The iliac crest is a particularly important bone structure in medicine, as it contains large amounts of bone marrow. It is often used as a source of red bone marrow cells and stem cells for bone marrow transplant procedures.everal important hip, back, and abdominal muscles have their origin at this bone.
