The collection of the Insect Museum of West China has received 3 Guinness World Records certificates, and 2 holders of them are displayed on this picture.
On the upper left corner is the world's largest aquatic insect, Acanthacorydalis fruhstorferi. The wingspan of a male specimen in our collection reached 21.6 cm, creating the Guinness World Record. Later, we collected a larger individual with a wingspan of more than 23 cm. We can compare the width of its wings with that of 2 praying mantises and 1 dragonfly next to it.
In the middle of the picture is the world's longest insect, Phryganistria chinensis Zhao, which is a new species found by our museum. With a maximum individual length of 64 cm, it is the record holder among nearly one million species of insects known in the world. Next to it, we can see a larva that is hatching from the egg and a specimen of a newly hatched larva. After each molting, the body length of this insect increases by about 1/3. After 7 times of molting, it becomes adult.
On the bottom of the picture, there are a few representative giant beetles. From right to left: the world's longest beetle, Macrodontia cervicornis; the largest beetle in China, Cheirotonus jansoni; Southeast Asian giant, Atlas beetle (Chalcosoma atlas); African giant beetle, Goliathus orientalis; and a common giant beetle in eastern Asia, Japanese rhinoceros beetle (Trypoxylus dichotomus).
