Web spiders are good at what’s call “ballooning,” in which they allow gusts of wind to send the aloft in the hope of meeting mates elsewhere. Apparently, they can reach the stratosphere and return to earth, saying, “‘Sup, dude?” on a different continent. But hunting spiders are not capable of this. Long ago, they had to walk, but human transportation has given them a, uh, lift? The black widow spider, a hybrid of web and hunting spiders, is know for hitchhiking its way from its native Australian to various locations via lumber trade. They are known for their hourglass-shaped abdomen and for residing in dark, dank places. My grandfather, a famous etymologist, had one bite him once and had to be hospitalized (that’s how they studied spider toxicity in the day). Apparently, they’ve shown up in Kumamoto. If you see any spider that looks like this, call the authorities. - William https://kumanichi.com/articles/271471
