Swallowtail caterpillars are the larval stage of swallowtail butterflies, belonging to the Papilionidae family. These caterpillars are fascinating creatures with unique characteristics.
*Identification:*
1. Body shape: Green or yellowish-green, elongated, and cylindrical. 2. Size: Typically 1-5 cm (0.4-2 inches) in length. 3. Head: Distinctive head with antennae and a horn-like structure (caudal horn). 4. Body markings: Stripes, spots, or patches, varying by species.
*Behavior:*
1. Feeding: Herbivorous, feeding on specific host plants. 2. Defense: Release foul-smelling fluid from their bodies or display warning colors. 3. Social behavior: Some species aggregate, while others are solitary.
*Host Plants:*
1. Carrot family (Apiaceae): Dill, fennel, parsley. 2. Citrus family (Rutaceae): Orange, lemon, grapefruit. 3. Laurel family (Lauraceae): Bay, avocado.
*Life Cycle:*
1. Egg: Female butterflies lay eggs on host plants. 2. Larva (caterpillar): Eats, grows, and molts several times. 3. Pupa (chrysalis): Caterpillar transforms into a butterfly. 4. Adult: Emerges, mates, and starts the cycle anew.
*Interesting Facts:*
1. Some species have adaptations to avoid predators, like eyespots or mimicry. 2. Swallowtail caterpillars can sequester toxins from host plants for defense. 3. They have unique silk production, using spinnerets to create silk threads.
Biological entities called obelisks have been hiding – in large numbers – inside the human mouth and gut. These microscopic entities, which were recently discovered by a team at Stanford University, are circular bits of genetic material that contain one or two genes and self-organise into a rod-like shape.
