Apart from filling the air with an earsplitting 94 decibel drone, the cicada known as the kumazemi is tearing up Japan's fiber optic internet system. Two to thee inches long, the black
cicada (Cryptotympana facialis), endemic in the warmer parts of Japan apparently mistakes fiber optic cables for dead branches suitable for egg laying, and uses its hypodermic-sized ovipositor to riddle them with millimeter holes. Trying to bug a conventional phone line this way can result in insect electrocution, but the cicadas find optical cables perfectly benign.
Once hatched , their larvae quickly wriggle into the optical junctions and etalon spaces, crashing the local net. Nippon Telephone and Telegraph West Corporation has responded to over 1000 such attacks in the Osaka area by adding protective layers and redesigning cables without the bark-like grooves cicadas mistake for prime real estate.
