What is the World's Biggest Insect?
For sheer length you can't beat a female Giant Walking Stick (Phobaeticus serratipes).Found in Malaysia and Singapore,looking like an assemblage of twigs,it is perfectly camouflaged among the branches where it lives.The longest specimen on record was an amazing 21.8" (55.5cm).Some people even keep these huge insects as pets.
The Giant Walking Stick may be long,but it doesn't weigh much.For that you have to turn to the giant scarab beetles.Among them,entomologists have settled on 5 contenders:
A shorter but far thicker competitor is the Acteon Beetle (Megasoma acteon) of South America.Males can grow to 5.3" (13.5cms) long by 1.6" (4cms) thick.
The Elephant Beetle (Megasoma elephas) found in Mexico and Venezuela has a shorter body than the Aceton,but a longer snout,making its total recorded length 5.4" (13.7cms).
Bringing up the rear are two species of Goliathus:regius and goliatus,both measuring in at 4.3" (11cms).
In 1874 the Rev.J.G.Wood published Insects Abroad,in which he claimed to have in his possession a 9" (22.8cm) South American Longhorn Beetle (Titanus).A specimen this large has never been documented since,and no one is quite sure what method he used to measure the bug.Therefore the accepted recorded length remains at 6.5" (16.7cms),which still leads the top five contenders.
