We study the diversity and evolution of arthropods. Particularly, we are interested in reconstructing the tree of life and understanding the ancient and on-going associations between humans and the arthropod species in our everyday lives. Whether learning about the mites on your face, the bugs in your house, or discovering new fly species, we look to engage the public in the process of doing science and in the thrill of discovery.
Lab News
- This May our research was featured on NOVA! Mites start 7 min. in. Check it out!:
- Oct. 2017 Two new papers out this week! Bugs in houses in Scientific Reports and a 1000+ taxon phylogeny of early brachyceran flies in Systematic Entomology. Here are summary figs from both:


- 11/1/17 Cal Academy scientists, including fly expert, Keith Bayless (@Keithing, research associate with the Trautwein lab) just got back from a biodiversity survey on Penang Hill @TheHabitatPH, Malaysia. Hundreds of species were documented in hopes of designating the rainforest as a UNESCO Biodiversity site.
- Look for us on NOVA next spring! Our face mite sampling team- postdoc Misha Leong, intern Michael Bennett, research volunteer Doris Won, postdoc Matt Van Dam, and my boss Shannon Bennett scraped faces for hours to find just one glorious mite in one lucky man’s ear wax. What a day.
- Soon, our research on the diversity of arthropods living in houses will be featured on the CBC show The Nature of Things. Last August, we spent a week filming our team sample bugs in a house in Toronto, and ate poutine in our down time. It was a ton of fun.

- We discovered a new species of bee fly! Undergraduate interns, Natalia Maas and Zachary Larmore, tirelessly stared at flies under a microscope for months in the summers of 2013 and 2014…and all they got was a very cool new species of Thevenetimyia from Madagascar. Click to read about all the species discovered at the California Academy of Sciences this year.
- Postdoc Dr. Misha Leong published a new paper reporting that more types of arthropods are found inside houses in wealthy neighborhoods. Wait….wha?! Read all about it or just read it.
Matt Simon from Wired Magazine and author of The Wasp that Brainwashed the Caterpillar talks weirdest animals of 2016. Luck for us, two of them are insects.
