During bloom, the tip of the spadix is roughly human body temperature, which helps the perfume volatilize. The heated spadix creates a micro-convection in the cool ambient air, enhancing the transport of the scent. The heat helps to convince carrion-feeding insects that a dead body is present, attracting them to the inflorescence. [9]
If the larval diet contained pyrrolizidine alkaloids, then the coremata become large and the male will release up to 400 micrograms (0.4 milligrams) of hydroxydanaidal, but if it does not, then the coremata do not grow large and no scent is produced. [9] The larvae of C. gangis can cause extensive damage to the foliage of pomegranate trees. [7]

Selectivity refers to the insects ability to tell one odorant apart from another. Among blood-feeding arthropods, these compounds are commonly broken into three classes: short chain carboxylic acids, aldehydes and low molecular weight nitrogenous compounds. [5] Insects have been used as a model system to study mammal and especially human olfaction.
Geosmin (/ dʒ i ˈ ɒ z m ɪ n / jee-OZ-min) is an irregular sesquiterpenoid with a distinct earthy or musty odor, which most people can easily smell. The geosmin odor detection threshold in humans is very low, ranging from 0.006 to 0.01 micrograms per liter in water. [1]
Five species are only found at high elevation in South Island. The scree wētā D. connectens lives about 1,200 m (3,900 ft) above sea level [9] and freezes solid when temperatures drop below −5 °C (23 °F). [10] Though the alpine species tend to be smaller on average than those other ground dwelling species. [3]
