Heard  about a plant that can turn into a worm in winter and then reverses back again in summer. Supposed to be found in the Himalayas and Tibet. It is pretty interesting.

Its a symbiotic parasitic relationship between a fungi and larvae. Not really a plant/worm.

Actually they recently discovered that the root systems of plants actually do not absorb nutrients as previously thought. Its the mycorrhiza that forms a symbiotic relationship with the roots that helps the tree do that. Plant biology is fascinating. There are fungi that can grow miles wide below the soil surface. So many symbiotic relationships in nature, its amazing.

yes it is interesting. Apparently due to its huge demand these plants are highly priced, Cordyceps sinensis.

The "caterpillar" [technically it is a larva, since it is hairless] prone to infection by the fungus lives underground in alpine grass and shrublands on the Tibetan Plateau and the Himalayas at an altitude between 3000m and 5000m. Spending up to five years underground before pupating, the caterpillar is attacked while feeding on roots. The fungus invades the body of the Thitarodes caterpillars, filling its entire body cavity with mycelium and eventually killing and mummifying it. The caterpillars die near the tops of their burrows. The dark brown to black fruiting body (or mushroom) emerges from the ground in spring or early summer, always growing out of the forehead of the caterpillar. The long, usually columnar fruiting body reaches 5-15 cm above the surface and releases spores.

In Nepal caterpillar fungus is found on the subalpine pastures in Dolpo in Karnali Zone and Darchula in Mahakali zone. It is also common in Bhutan and India's Himachal Pradesh and Uttarakhand Himalayas. Reports of distribution outside of "High Asia" are erroneous and relate to other species of Cordyceps, e.g. Cordyceps militaris.

It is not certain how the fungus infects the caterpillar; possibly by ingestion of a fungal spore or by the fungus mycelium invading the insect through one of its breathing pores.

I've always wondered about insectivorous plants like Venus Fly Traps and Pitcher's Plant etc. They are almost like little carnivorous animals. I know people who own such plants and treat them like pets, feeding them flies and spiders.

I wonder if these plants are also good in getting rid of mosquitoes and occassional flies (without destroying the ozone layer).
Generally I do let mosquitoes bite me sometimes. There must be some good in it, cannot be all bad eg. help me get rid of excess old blood.LOL
