How long do insects live? - Methusalems with six legs
How long do insects live? Methusalems with six legs Conservation A pine tree sprouted in California more than 5,000 years ago and is still standing today. The oldest spruce growing in central Sweden is even 9,550 years old according to the results of the 14C analysis. Individual greenland sharks roam the seas for over 400 years. Giant tortoises can reach 200 years. The maximum age for a person is estimated to be around 120 years. An insect's life doesn't last that long. But how old do these animals get? & Auml; The largest European goat, the stag beetle (Lucanus cervus), is getting older. It lives up to eight years as a larva on the rotten wood of dead trees in their root area. In the autumn before leaving, it pupates and turns into a fully grown stag. However, he stays in his doll's cradle underground for the winter. The deer do not leave their hiding place until the following early summer. The males appear about a week before the females, as their pupa cradle is less deep in the ground and therefore warms up more quickly. But life as a "real" boy only lasts for a short time. After a few weeks it will be over, with the life expectancy of the females being slightly higher than that of the males. T he beefs spend the longest time of their lives as larvae. This also applies to the seventeen-year-old cicada (Magicicada septendecim) in eastern North America. The larval development takes 17 years. After this long time, billions of cicadas transform into adult cicadas almost at the same time. After a few days, the mating takes place, with which the task and thus the life cycle of the male is over. The females die after laying the eggs. After four to six weeks, the seventeen-year-old cicadas will disappear again. The larvae spend their time in the ground where they suckle on roots. There is also an insect in North America that also gets quite old - but spends most of its life not as a larva, but as a fully-grown animal: a beetle, which the Americans Blue Death Feigning Beetle ) and scientists call it Asbolus verrucosus. His body is covered with a blue layer of wax, which probably protects him from dehydration. Because he lives in Northern Mexico and in the hot, dry Southwest of the USA, including in the Valley of Death and the Mojave Desert. When disturbed, it often plays dead, a strategy not uncommon for insects to protect itself from enemies. These bugs are said to be able to survive for months without food and up to a year without water. Different sources speak of a lifespan of 7 to 20 years. T he world record holder seems to be a beef: The magnificent golden beef (Cypriacis aurulenta), again a North American species. It colonizes the western United States and Canada. Occasionally, it also reaches other parts of the world with imported wood. The larvae usually develop within five years. In exceptional cases, however, it can take several decades. It is reported that the maximum age is around 50 years. The females are active between June and October. They lay the eggs, e.g. Douglas fir trees damaged by fire or other influences, various pines or other conifers. The larvae develop in the wood, which can lead to economic damage for the wood industry. So insects are nowhere near as old as representatives of many other animal groups. Most species have only a short life. In individual cases, however, insects can reach an astonishingly old age. Dr. Martin Lillig T he life expectancy of insects can be quite different within a species. While the males die after a very short time, the workers of the blood-red predatory ant (Formica sanguinea), one of the red forest ant species, can reach a maximum of about five years, while the queen can do it Can bring 15 to 20 years. In captivity, a queen of the black garden ant (Lasius niger) even lived to be 29 years old. Such an old age, however, seems hardly attainable under natural conditions. Photo: Dr. Martin Lillig T he number of dots shows the age of the ladybug - many people still believe that today. If this were correct, there would only be seven-year-old seven-point ladybirds (Coccinella septempunctata). And the Asian ladybug (Harmonia axyridis), which has also been flying in Saarland since 2004, would reach an age of up to 19 years. The yellow 22-point ladybug (Psyllobora vigintiduopunctata), which is also frequently encountered, has five on the pronotum in addition to the 22 points on the wing covers. On the other hand, there are also ladybugs without any points. How old would they be? In reality, ladybugs live a maximum of three years old. Hirschkäfer (male). Environment magazine Saar 4/2016 19
