Insects<span>, which are a type of </span>arthropod<span>, are easily the most numerous group of multicellular </span>organisms<span> on the planet, with about a million species identified so far. The title of heaviest insect in the world has many rivals, the most frequently crowned of which is the </span>larval stage<span> of the </span>goliath beetle<span>, </span>Goliathus goliatus<span>, the top size of which is at least 115 g (4.1 oz) and 11.5 cm (4.5 in). The largest confirmed weight of an adult insect is 71 g (2.5 oz) for a </span>giant weta<span>, </span>Deinacrida heteracantha,[1]<span> although it is likely one of the </span>elephant beetles<span>, </span>Megasoma elephas<span> and </span>Megasoma actaeon<span>, or </span>goliath beetles, both of which can commonly exceed 50 g (1.8 oz) and 10 cm (3.9 in), can reach a higher weight.<span>[1]</span>
Very simply, I think that they may block the sun's rays from reaching the Earth, cooling down the planet, or they may eventually end up being turned into acid rain and rain back down to the Earth.
