Millipedes can be an unwanted nuisance particularly in greenhouses where they can potentially cause severe damage to emergent seedlings. Most millipedes defend themselves with a variety of chemicals secreted from pores along the body, although the tiny bristle millipedes are covered with tufts of detachable bristles. Its primary defence ...
They are some of the few known bioluminescent species of millipedes, a class of about 12,000 known species. [4] Motyxia sequoiae glows the brightest and Motyxia pior the dimmest. [5] Light is emitted from the exoskeleton of the millipede continuously, with peak wavelength of 495 nm (the light intensifies when the millipede is handled). [6]
Wild wedge-capped capuchin monkeys (Cebus olivaceus) self-anoint with millipedes (Orthoporus dorsovittatus).Chemical analysis revealed these millipedes secrete two benzoquinones, compounds known to be potently repellent to insects [6] and the secretions are thought to provide protection against insects, particularly mosquitoes (and the bot flies they transmit) during the rainy season.
Centipedes eat other household pests, so you may actually want them around.
The great majority (80–99.99%) of individuals born do not survive to reproductive age, with perhaps 50% of this mortality rate attributed to predation. [1] In order to deal with this ongoing escapist battle, insects have evolved a wide range of defense mechanisms.
Pill millipedes are relatively short-bodied compared to most other millipedes, with only eleven to thirteen body segments, [2] and are capable of rolling into a ball when disturbed, as a defense against predators. This ability evolved separately in each of the two orders, making it a case of convergent evolution, rather than homology.
Millipedes in this order grow and develop through a series of molts, adding segments and legs until they reach a fixed number in the adult stage, which is the same in a given species. Adults continue to molt, but they do not add segments or legs. This mode of development is known as hemianamorphosis. [12]
