![A Defensive Citrus Swallowtail caterpillar - showing Osmeterium The osmeterium is a defensive organ found in all papilionid larvae, in all stages.[1] The organ is situated in the prothoracic segment and can be everted when the larva feels threatened. The everted organ resembles a fleshy forked tongue (not unlike a snake tongue), and this along with the large eye-like spots on the body might be used to startle birds and small reptiles. The osmeterial organ remains inside the body in the thoracic region in an inverted position and is everted when the larva is disturbed in any way emitting a foul, disagreeable odor which serves to repel ants,[2] small spiders[3] and mantids.[4] To humans, this odour is rather strong but pleasant, usually smelling like a concentrated scent of the caterpillar’s food plant and pineapple.
The constitution of the osmeterial secretion varies from species to species and contains monoterpene hydrocarbons, sesquiterpenic compounds or a mixture of aliphatic acids and esters

I have an interest in birds, recently Insects and wildflowers. I am continuing to learn how to see. I am a fortunate person. I am discovering new dimensions of nature every day.
