Oh? In California?
That leads to such questions as:
- "Does California have brown recluse spiders?"
- "Do millipedes really have 1000 legs?"
- "Are baby scorpions deadlier than adults?"
Those are some of the topics that UC Davis doctoral candidates Emma Jochim and Xavier Zahnle of the Jason Bond arachnology lab will discuss when they dispel myths about spiders and millipedes at the Bohart Museum of Entomology open house on Saturday, March 18. The theme: "Many-Legged Wonders."
The Bond lab's question-and-answer session about spider myths is set from 1 to 1:30 p.m. First-year doctoral student Iris Quayle will moderate. Lab members also will show some "rarer live arachnids such as 'vinegaroons' and 'whip spiders' in addition to tarantulas and scorpions," Jochim said. "We will also have millipedes that people can handle and many species of isopods."
Professor Bond is the Evert and Marion Schlinger Endowed Chair in Insect Systematics, UC Davis Department of Entomology and Nematology, and associate dean, College of Agricultural and Environmental Sciences.
- Princess Herbert, a Brazilian salmon-pink bird-eating tarantula (Lasiodora parahybana), age estimated to be around 20 (current oldest resident)
- Peaches, a Chilean rose hair tarantula (Grammostola rosea)
- Coco McFluffin, a Chaco golden knee tarantula (Grammostola pulchripes)
- Beatrice, a Vietnamese centipede (Scolopendra subspinipes), newest resident
- Two black widows (Latrodectus hesperus)
- One brown widow (Latrodectus geometricus)
Among the other residents are Madagascar hissing cockroaches, a giant cave cockroach, stick insects, a bark scorpion and ironclad beetles. A family arts-and-crafts activity is also planned.
The family arts-and-crafts activity, being planned by Jochim, will be molding arachnids and myriapods using model clay.
The Bohart Museum, directed by UC Davis distinguished professor Lynn Kimsey, houses a global collection of eight million insect specimens, plus the petting zoo and a gift shop stocked with insect-themed books, posters, jewelry, t-shirts, hoodies and more. Dedicated to "understanding, documenting and communicating terrestrial arthropod diversity," the Bohart Museum was founded in 1946 and named for UC Davis professor and noted entomologist Richard Bohart. The insect museum is open to the public Mondays through Thursdays, from 8 a.m. to noon, and 1 to 5 p.m.

A BioBlitz is set from 9 to 11 a.m., Saturday, April 29 in the UC Davis Arboretum and Public Garden. It's being hosted by UC Davis doctoral student Grace Horne of the Department of Entomology and Nematology.
Participants will meet in at the Wyatt Deck (previously the BioBlitz was scheduled for the Carolee Shields White Flower Garden and Gazebo.)
"I am excited about the location change because we will be located next to two biodiversity hubs: The T. Elliot Weier Redwood Grove and the Mary Wattis Brown Garden of California Native Plants," said Horne, a member of the laboratory of urban landscape entomologist Emily Meineke, assistant professor, UC Davis Department of Entomology and Nematology.
Reservations (free) are underway here.
“We need your help to track and identify the wildlife in Davis!" said Horne, a member of the laboratory of urban landscape entomologist Emily Meineke, assistant professor, UC Davis Department of Entomology and Nematology. "Participants will take photos of plants, animals, and fungi, and upload these observations to the community science platform, iNaturalist. All you need to bring is a smartphone or a photo-taking device. We will have a table with small lenses, bug boxes, field guides, insect specimens, and more to help you make observations of wildlife. Local experts will also be available to assist in identifying the wildlife."
This event will be hosted in coordination with the City Nature Challenge Sacramento. The City Nature Challenge (CNC) is an annual international competition among cities with the goal of documenting the most biodiversity within a four-day period.
This year the challenge will occur from April 28 to May 1, "so any observations of wildlife that are uploaded to iNaturalist will contribute to the 2023 CNC," Horne said. "At the end of the CNC, the region with the most observations wins. We are looking to make as many quality observations as we can during the Davis Bioblitz, so stop by the Shields Gazebo to help contribute observations to the Greater Sacramento Region!”
Horne's undergraduate thesis about the effects of the decline of ash trees on native caterpillars, scored the cover of the February edition of the journal Environmental Entomology. The paper, “Specialist Herbivore Performance on Introduced Plants During Native Host Decline,” is co-authored by Ria Manderino of the Oak Spring Garden Foundation, Upperville, VA and Samuel Jaffe of The Caterpillar Lab, Marlborough, N.H. “Our publication highlights the importance of multispecies assessments of host plant acceptance,” said Horne, who studies plant-insect interactions, urban ecology, global change biology, natural history and community science in the Meineke lab.

Well, they're huddled inside their colonies as California storms erupt with a vengeance reserved for politics.
The bees venture out...one here...one there...on sun breaks, but never is the nectarine tree a'buzzing as it did last year.
"So far things could be worse," UC Davis butterfly guru Art Shapiro distinguished professor of evolution and ecology, wrote in a group email (his "posse") on March 13. "Unfortunately, there appears to be no break through the end of the month, with never more than two consecutive dry days in the entire stretch and temperatures remaining well below normal. I don't think it's an 1861-62 scenario...yet...glub.."
Shapiro, who has monitored the butterfly populations of central California for 50 years and maintains a research website, Art's Butterfly World, tracks both butterflies AND temperatures--past, present and future.
On a scale not seen since 1861-62? That references the Great Flood of 1862, "the largest flood in the recorded history of Oregon, Nevada, and California, occurring from December 1861 to January 1862," according to Wikipedia.
Wikipedia says "it was preceded by weeks of continuous rains and snows in the very high elevations that began in Oregon in November 1861 and continued into January 1862. This was followed by a record amount of rain from January 9–12, and contributed to a flood that extended from the Columbia River southward in western Oregon, and through California to San Diego, and extended as far inland as Idaho in the Washington Territory, Nevada and Utah in the Utah Territory, and Arizona in the western New Mexico Territory. The event dumped an equivalent of 10 feet (3.0 m) of water in California, in the form of rain and snow, over a period of 43 days. Immense snowfalls in the mountains of far western North America caused more flooding in Idaho, Arizona, New Mexico, as well as in Baja California and Sonora, Mexico the following spring and summer, as the snow melted."
Indeed, Shaprio could hold a second job as a meteorologist, but he says this: "As you know, I adhere to the 'weatherman's philosophy,' i.e. predict the worst because if it doesn't happen people will feel relieved, whereas if you didn't predict it and it happens people will want to kill you. May it not happen--any of it."
Meanwhile, we welcomed another sun break yesterday. So did the nectarine tree and the honey bees.

If you said "14," go to the head of the class.
Is it an insect? No, it's a crustacean.
When the Bohart Museum of Entomology hosts an open house on "Many-Legged Wonders" from 1 to 4 p.m., Saturday, March 18, among the critters showcased will be spiders, millipedes, centipedes, scorpions, tarantulas, and yes, isopods.
The event, free and family friendly, takes place in Room 1124 of the Academic Surge Building, 455 Crocker Lane, UC Davis campus.
Elijah Shih, a third-year UC Davis transfer student studying neurobiology, physiology and behavior, will show his isopods. “Isopods come in many morphs and sizes," he says. "There are many colorful and beautifully patterned isopods, some natural, some man made. Isopods are crustaceans and require moisture to breathe and molt properly. Some species have the ability to conglobate or roll up in to the ball where as others do not. They are great for helping create a bioactive system for reptiles, planted tanks, and a great feeder for young reptiles and amphibians.”
“There are many isopod species in the world," Shih related, “and at least five common isopod species that are found in California: Porcellio laevis, Porcellio scaber, Armadillidium vulgare, Porcellio dilatatus, and Cubaris marina. Their morphs are considered wild type.”
Shih, who hopes to pursue a career in veterinary medicine, said he houses “many reptiles, both aquatic and terrestrial, such as the box turtle and gargoyle gecko. I wanted to create bioactive environments for my reptiles—(mainly to not have to pick up the feces)-- so I looked for ways to make that possible. I need something that was small, agile, prolific, and safe to be eaten. Isopods, better known as Rollie pillows or pill bugs, are the best solution for me. I had my isopods, but to complete the cleanup crew, I added springtails to help clean up any leftover food, but more importantly, the mold.”
Tabatha Yang, education and outreach coordinator for the Bohart, announced that doctoral candidates Emma Jochim and Xavier Zahnle of the Jason Bond arachnology lab will dispel myths about spiders and millipedes at a question-and-answer session from 1 to 1:30. Doctoral student Iris Quayle will moderate.
From 1:30 to 4 p.m., will be the general open house with a showing of live animals and specimens. Bohart Museum research associate Brittany Kohler, the "zookeeper" of the Bohart petting zoo, says the current residents include:
- Princess Herbert, a Brazilian salmon-pink bird-eating tarantula (Lasiodora parahybana), age estimated to be around 20 (current oldest resident)
- Peaches, a Chilean rose hair tarantula (Grammostola rosea)
- Coco McFluffin, a Chaco golden knee tarantula (Grammostola pulchripes)
- Beatrice, a Vietnamese centipede (Scolopendra subspinipes), newest resident
- Two black widows (Latrodectus hesperus)
- One brown widow (Latrodectus geometricus)
Among the other residents are Madagascar hissing cockroaches, a giant cave cockroach, stick insects, a bark scorpion and ironclad beetles. A family arts-and-crafts activity is also planned.

Pincebourde, a research director at the National Centre for Scientific Research (CNRS), France, will speak on "The Key Role of Microclimates in Modulating the Response of Ectotherms to Climate Change," at 4:10 p.m. (Pacific Time) on Wednesday, March 15 via Zoom. The Zoom link:
https://ucdavis.zoom.us/j/95882849672
Pincebourde, a research director at the (CNRS), France, says in his abstract: "In a warming world, species may buffer to some extent part of the environmental changes by exploiting the microclimates that are available across space and time. My presentation will focus on the role of the leaf surface microclimate, and in particular temperature, in driving the vulnerability of insects to climate change. I will exemplify the framework we apply to investigate this role. Our approach is deeply rooted into a multidisciplinary background, relying on physics, physiology and ecology of both plant and animal sciences. The microclimatic effects can be quite subtle and mechanistic approaches are fundamentally needed to depict the complexity of the interaction between plant, insect and climate."
On Research Gate, Pincebourde explains that his work "focuses on the role of microclimates in modulating the response of ectotherms (mostly insects) to climate change. I use ecophysiological approaching mostly relying to thermal ecology, connected to the biophysical ecology of organisms. I integrate both temporal and spatial issues of thermal variability. My research has connection with conservation biology by identifying novel or unsuspected interactions between (micro) climates and organisms."
Urban landscape entomologist Emily Meineke, assistant professor with the UC Davis Department of Entomology and Nematology, and coordinator of the department's weekly seminars, will host the seminar and introduce him.
Pincebourde holds a doctorate (2005) from the Institute of Research on Insect Biology (IRBI), France, a joint research unit of the University of Tours and CNRS. He studied for his doctorate with Professor Jérôme Casas. Pincebourde then completed postdoctoral fellowships at the University South Carolina (2006-2007), supervised by Professor Brian Helmuth, and at IRBI (2008-2009), working with Professor Casas's team that studied the ecology of multitropic systems and biomimetism.
Pincebourde joined CNRS as a research scientist, second class, in 2009 and advanced to first class in 2015. Since 2018, he has been in charge of the IRBI's organism-environmental interactions team, known as INOV or the INteractions Organisme-enVironnment.
He has published his work in a number of journals, including Frontiers in Ecology and Evolution, Ecological Monographs, Agriculture and Forest Entomology, Functional Ecology, Journal of Thermal Biology, Biotropica, with papers pending in Global Change Biology and Freshwater Biology. He is a member of the editorial board for American Naturalist.
The UC Davis Department of Entomology and Nematology's winter seminars are held on Wednesdays at 4:10 p.m. in 122 Briggs Hall. (See schedule.) She may be reached at ekmeineke@ucdavis.edu for technical issues.
