The newly-identified specimen is the only cockroach of its variety, ectocbiid, to be discovered in amber from the Dominican Republic.
It is a known fact that cockroaches are the world's oldest pests. Their extraordinary resilience helps them survive in temperatures below freezing, and can even withstand pressures of up to 900 times their body weight, said Poinar.
There are more than 4,000 species of roaches crawling all over the Earth. Fortunately, only 30 types of those share a“So what caused these cockroaches to become extinct when it is so difficult to get rid of them today?” wondered Poinar. Because they don't care about walking through sewage or decaying matter, Poinar stated that roaches are likely to contaminate the surfaces they touch."They are considered medically important insects since they are carriers of human pathogens, including bacteria that cause salmonella, staphylococcus, and streptococcus," Poinar said. "They also harbor viruses. And in addition to spreading pathogens and causing allergic reactions, just their presence is very unsettling.
Cockroaches also contain enzymes that protect their toxic substances. This is one of the reasons they cannot be easily evicted. There's also evidence that they're developing resistance to many insecticides. Oh, the horror.from homes once they’ve taken up residence can cause a lot of stress," Poinar said. "Many might say that the best place for a cockroach is entombed in amber.
The new cockroach species is the latest of the many scientific discoveries made by Poinar, who is an international expert in using plant and animal life formsA small, male cockroach in Dominican amber is described as Supella dominicana sp. n. . The dark tegmina, which are equal to the length of the abdomen, have a yellow cross bar and a central stripe giving the illusion that the body is divided into two halves.
