Jungle Survival Tips

    Avoid plants with white or yellow berries.
    Don't eat mushrooms. Some are safe, but many are highly toxic even deadly, so it's not worth the risk.
    Avoid plants with thorns.
    If it tastes bitter or soapy, spit it out.
    Steer clear of shiny leaves.
    Stay away from plants with leaves in groups of three.
    Stay away from plants with umbrella-shaped flowers.
    Avoid beans or plants with seeds inside a pod.
    Milky or discolored sap is a warning sign.
    Avoid anything with an almond smell.
    Steer clear of brightly colored insects.
    Avoid insects that are extremely pungent.
    Don't eat hairy critters or bugs that bite or sting.

You can also use the universal edibility test to check whether a plant is edible. It involves steps like rubbing the plant on your skin and lips and holding it in your mouth to see if there's an adverse reaction.
Fruit can be found throughout the jungle. Depending on where you are, you can find everything from mangoes and bananas to wild yams and sugarcane. Coconuts are a good food source in tropical jungles, as is sugarcane, figs, papaya and taro root. Familiarize yourself with local edible fruits before you travel to any jungle or rainforest.

Insects are another good source of protein. More than 1,400 varieties are eaten regularly everywhere. Worms, grubs and termites are everywhere in the jungle and are all a great protein source. If you had fresh water, you could survive for months on insects alone. Beetles can also make for a hearty meal, but some carry parasites. A good way to make sure you're safe is to cook it. A good boiling or slow roast will usually negate the effect of harmful toxins.

Down in Jungleland

Here a few more survival tips if you find yourself lost in the jungle:
If you don't have any mosquito repellent, tie a shirt over your head and let it hang down over your neck. Rub mud on your exposed skin. Once it dries, it will form a crusty barrier against mosquitoes.
 Use campfire smoke at dawn and dusk to help repel insects.
 Shake out your shoes or boots before you put them on each day. Scorpions and spiders like to hide inside them.
 Rivers and streams often lead to human settlements.
  Look to monkeys for advice on what kinds of fruits and plants are safe to eat.
    Leave piles of rocks along your trail as a rescue signal.
    Break branches at eye-level on your path to let rescuers know which direction you're traveling.
    Use a smoke signal to alert rescuers. Find an open spot for the smoke to rise, then cover the fire with wet palm fronds for several seconds at a time in bursts of three, the signal for distress.
