NYPost Rich executives from around the world aren’t the only foreigners attracted to the trendy neighborhood around High Line Park. Meet Periplaneta japonica, a species of cockroach that can withstand New York winters outdoors and has never before been seen in the United States. They were first spotted in 2012 by an exterminator in the park. Scientists suspect they stowed away in the soil of plants imported to decorate the former elevated freight line.
Just great, a new species of cockroach, which can withstand freezing temperatures has invaded New York City. As if we did not have enough problems with regular cockroaches, which get killed off in the cold (not as if that matters, they are already inside of our warm apartments and delis), we now have freeze proof cockroaches which will be ice skating at Rockefeller Center this winter.
A little more about the newest disgusting creature to invade NYC, the Periplaneta japonica, or Japanese cockroach:
Wikipedia The Japanese cockroach (Periplaneta japonica Karny), also known as the Yamato cockroach, is a cockroach native to Japan that is adapted to cooler northern climates. It has a flexible univoltine or semivoltine (one or two year) lifecycle, and is unsual in being able to spend two winters as diapause nymphs before reaching maturity.
Nymphs have been observed in the wild hibernating in sub-freezing temperatures during winter months in snow-covered habitats. Overwintering nymphs were able to survive laboratory supercooling experiments in the -5 °C to -8 °C temperature range, enduring twelve hours of tissue freezing, as well as recover from burial in ice. The ability to walk on ice was also found to be unique among several cockroach species tested.
Initial first-instar nymphs are dark brown, with white or brownish white tips of the maxillary and labial palps. Adults measure 25-35 mm in length, and have a shiny, uniformly black to blackish-brown body, with brown tarsi and maxillary and labial palps. The adult male’s wings extend slightly beyond the body’s length, while the female’s wings are around half the body’s length.
Unlike most cockroaches, the major hydrocarbon in P. japonica’s cuticular lipids is cis-9-nonacosene. Males have significant amounts of cis-9-heptacosene not found on females. Glucose, myo-inositol, scyllo-inositol and trehalose were found in overwintering nymphs and are thought to be a factor in their freeze tolerance.
Primarily an outdoors species, populations are adaptable to living indoors in houses and buildings where food is stored, prepared, or served.
P. japonica nymphs that are alone or in sparse populations accumulate a viscous secretion along its rear dorsal surface, droplets of which it can splash some distance through a shaking action. A study found that the presence of an aggressive species of ant, ‘’Formica exsecta’’, triggered this defensive response, rendering the ants helpless.
Originally from Japan, P. japonica has spread to China, Korea and Russia.
The species was found in New York City in 2012, the first time the species was found in the United States. It was found by an exterminator in a park beneath plantings outside a building, and was able to survive over a cold winter. “They were not buried in the soil but were found around stones and planting materials.” Scientists who confirmed the identity of the species through genetic testing theorize that it may have been imported in the soil of ornamental plants used in the park.
