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.
There is an iliac tubercle on the widest point of the iliac crest. This is where the iliotibial band attaches to the hip. The iliotibial band attaches the muscles that extend, abduct and laterally rotate the hip and stabilize the knee. Many of the important abdominal and core muscles are attached to the iliac crest.
