Image credit: Sunbin Huang & Mingyi TianXuedytes bellus, a cave dwelling beetle was discovered in a cave in Guangxi Province, China. Like much of southern China, this is in a vast landscape riddled with caves. This new species of beetle is about 9 mm in length, with elongated head and prothorax. First pair of legs are attached to the body segment immediately behind the head. Beetles that evolve in the darkness of caves often take on a similar set of characteristics, including narrow bodies, spider-like appendages and loss of wings, eyes and pigmentation. Such beetles are an example of convergent evolution. Suggested Reading

110 years ago, one man set out to rid Texas of Malaria – with the help of what was then a very unlikely source… bats! Dr. Charles A. Campbell had a simple plan. He knew that bats eat mosquitoes, and believed that if he could entice thousands of bats to live in Malaria-ridden areas, they would single-wingedly eradicate the disease. After years of fruitless experimentation with small roosting boxes, he decided to go BIG, with a 30-foot tower containing roosting shelves, guano lures, and a meal plan – three large hams! The $500 contraption was, alas, a flop. Campbell realized that he didn’t understand bats enough to provide suitable homes. He spent months studying caves and roosts to learn what bats needed most. In 1911 he constructed a new, improved tower at Mitchell’s Lake, where 90% of the locals were sick with Malaria. Within 4 years, Mitchell’s Lake was M…

Of the identified 65 species, two species live on your face, they are Demodex folliculorum and Demodex brevis. Two species live in slightly different areas, D. folliculorum lives in pores and hair follicles and D. brevis prefers to live deep inside your sebaceous glands. The adult mites are only 0.3–0.4 mm long, with D. brevis slightly shorter than D. folliculorum. These mites are mostly seen associated with the face as the face has larger pores and more sebaceous glands. They are also seen else where in the body including genital area and breasts.
