Ligature Strangulation. Strangulation is that form of asphyxia which is caused from constriction of the neck by ligature without suspending the body. Pulling a U-shaped ligature against the front and sides of the neck while standing at the back can cause death. It is of two types: [1] Strangulation by a ligature, and [2] manual strangulation or throttling.
What are the enemies of the monarch butterfly? The biggest threat to the monarch butterfly are wasps, bees, frogs, and especially people. Insects like to eat the eggs of monarch butterflies.
Actually, no. Monarch caterpillars do only eat plants in the Milkweed family (Asclepias spp), so if we want to help them out in our wildlife gardens, we still need to add these plants to our gardens. Monarch caterpillars do not feed on tomato plants, despite what may seem like circumstantial evidence to the contrary.
