Meganulon

Meganulon (メガヌロン, Meganuron?) were Mesozoic giant insects reanimated by mining operations in Kitamatsu village, Kumamoto Prefecture, in the 1956 kaiju eiga Rodan. (Presumably they are, like the titular daikaiju, Cretaceous.) The car-sized insects, which resembled overgrown earwigs, slaughtered several men before some were killed in a mine shaft. A mine collapse followed, separating engineer Shigeru from fellow miners and police. Before finding his way out of the mine, Shigeru witnessed the hatching of Rodan, who began to devour the comparatively tiny Meganulon.

Godzilla vs Megaguirus
The 2000 Godzilla film Godzilla vs. Megaguirus featured Megaguirus (メガギラス, Megagirasu?), an extinct species of dragonfly, based on the Meganulon, as Godzilla's adversary. According to the film, Meganula (also Meganuera) and Megaguirus had originated in China during Carbiniforous times. The insects follow an odonatan life cycle of which the Meganulon is the nymph stage. After a hemimetabolic interim the winged Meganula moult and take flight. Megaguirus was in fact the chosen queen among the colony and allowed to grow to massive size. As such, she is one of few decidedly female creatures of the genre.

Megaguirus's decendant was created when a weapon that would send Godzilla into another dimension allowed a giant insect to arrive on Earth and lay an egg which would later be discovered by a young boy and then hatch into a Meganulon. Megaguirus has numerous abilities. At top flight speed she vanishes into a blur, enabling her to surprise an opponent from an unexpected quarter. This high-speed flight also produces high frequency sonic waves capable of shorting out nearby electrical equipment. Her sharp wings can even cut steel and concrete. Her large abdomen ends in a vicious stinger used to pierce into an opponents hide and drain energy from it. During this process, the opponent is incapable of launching any additional energy-based attacks upon her.
