THE AMAZING SNOW PLANT


Image source

The Mycotroph family of plants manages to somehow survive without chlorophyll and photosynthesis. The strange looking snow plant (Sarcodes sanguinea), a red and fleshy parasitic plant, gets its nutrition from the fungi in the soil below it and its water from nearby confiners – therefor it is able to survive without doing the hard job of photosynthesis itself.

The snow plant is found in the western United States, including the Sierra Nevada range of California. Its name derives from the striking red flower that emerges from the sometimes still snow-covered ground in early spring (mid-may in the Sierra Nevada) (via). Scientists are not sure why the flower has such a bright red colour, presumably the bright red attracts pollinating insects in the rather shady forest floor areas where the snow plant grows.

The flowers of the snow plant point downwards once they open. The inside of a snow plant flower contains a large white ovary, which contains seeds when it matures. The plant also develops fruit that are colourful and fleshy when mature, but afterwards they dry out and fall off.

Roads will get you nowhere in this picturesque village. Giethoorn, a village in the Dutch province of Overijssel, is an international tourist attraction in the Netherlands. The old part of the village has no roads and all transport is done by water. All visitors are welcome to enjoy the beautiful scenery while on a Whisper Boat (a special electric powered boat, which makes no noise). Other activities tourists can enjoy are picnics, swimming, sailing and windsurfing.

THE WORLD'S HEAVIEST INSECT

The Heavyweight champion of the insect world

What is worst than coming face to face with a creepy crawly? Coming face to face with a giant creepy crawly!

New Zealand’s Giant Weta is the heaviest insect on the planet; weighing more than 71 g, this arthropod is heavier than a swallow. There are eleven species of giant weta, which are significantly larger than other weta or any other insect. The largest species of giant weta is the Little Barrier Island giant weta also known by the Maori name ‘wetapunga’, which means ‘god of ugly things’. These heavyweights have a body length of up to 10 cm, excluding their lengthy legs and antennae. They often live under rocks and bush floor debris and prefer a vegetarian diet.

At approximately two years of age the female will lay anything between a hundred and three hundred eggs. Unfortunately, the parents of the ‘little giants’ will die before the eggs hatch three to five months later. However spine-chilling they seem, they are in actual fact gentle giants and need to be respected and protected. Weta are at risk from being eaten by rats, trampling by stock and killed by forest fires.
