osmeterium การใช้

• The osmeterium is exists in all stages of the larvae.
• The tips of the tubercle are black and the osmeterium is dark red.
• The osmeterium of the caterpillar also helps to enhance the resemblance to a snake.
• It has a deep red osmeterium.
• The osmeterium is light indigo blue.
• The larvae have a reddish-orange forked gland, called an osmeterium just behind the head.
• When attacked, the larvae will expose the osmeterium, a Y-shaped organ typically folded up within the caterpillar.
• The deep red osmeterium and yellowish-brown head help distinguish it from the blue Mormon caterpillar which has a greenish head.
• As with other " Papilio " s there is a branched horn on the osmeterium which the larva extrudes when irritated.
• Swallowtails have a number of distinctive features; for example, the papilionid caterpillar bears a repugnatorial organ called the osmeterium on its prothorax.
• Instead, when threatened by a bird or other predator, they produce a forked, orange-coloured organ known as an osmeterium.
• The osmeterium normally remains hidden, but when threatened, the larva turns it outward through a transverse dorsal groove by inflating it with fluid.
• Some caterpillars, especially members of Papilionidae, contain an osmeterium, a Y-shaped protrusible gland found in the prothoracic segment of the larvae.
• The larvae feed on species of plants belonging to the Papaveraceae and Crassulaceae families, and like the other swallowtail butterfly larvae, possess an osmeterium.
• Like most swallowtails they have red wishbone shaped organ called the osmeterium which pops out from behind the head and releases a foul odor to warn off predators.
• When disturbed, the larvae can erect a reddish-orange coloured, osmeterium from behind the head which releases a citrus-like smell of rotting oranges.
• Like other swallowtail butterflies, when disturbed, the caterpillar erects its bright red osmeterium from behind the head, releasing the smell of citrus, to drive predators away.
• It has a defense against predators in the form of an " osmeterium ", which consists of retractable, fleshy projections behind its head that can release a foul smell if disturbed, which deters insects, but not birds.
