In your childhood, somebody probably gave you a jack-in-the-box toy, a music box that you crank up, and then the lid springs opens and out pops a wildly dressed clown, startling you and everyone around you.
A praying mantis sighting is something like that, but without the music box. You're walking in the garden and suddenly you notice that the Mexican sunflower, Tithonia rotundifola, appears to have an extra petal.
You look closer and you see a triangular head with bulging eyes. It's a praying mantis and it's looking right at you.
Such was the case recently when a female praying mantis, Mantis religiosa, popped up between the petals.
Jackie-in-the-box!
"Nice to meet ya, m'dear," she seemed to be saying. "Too bad you're not a bee."
Meet two real-life entomologists that studied bugs in school and now work with them for their job. Learn how they became interested in bugs, and the projects they work on.
You'll also learn about the common critters found around your home, and then make an insect collection. (bring all the dead bugs you can find!)
We will provide a box, pins, labels, and some bugs. Put bugs you find around your home in a jar and freeze them, then bring it to the workshop. You will take home a bug magnifier and bug net.
Where: Ag Center, Harvest Hall rooms D&E, 3800 Cornucopia Way, Modesto, 95358.
When: Saturday, October 5, 9:30 AM - 11:30 PM

*never try to catch bees or wasps, as they may sting you. You can usually find them already dead, laying on the ground.

It's beginning to look a lot like...Halloween.
If you haven't noticed, stores are gearing up for Halloween with assorted ghosts, goblins and ghouls for you.
We remember Halloween 2023 when a female migratory monarch fluttered into our pollinator garden. She checked out the milkweed (we had several native and one non-native species) and chose to sip nectar on the tropical milkweed, Asclepias curassavica, a non-native.
We managed to capture several images of her around 5:30 p.m. before she left on her journey to overwinter in coastal California.
The Center for Biological Diversity, headquartered in Tucson, says on its website: "Across their range, monarchs are threatened by pesticides, climate change, ongoing suburban sprawl, and fragmented and poisoned habitats as they navigate their way across the continent. They need a helping hand from the government, businesses and concerned individuals."
Threats? To that we'd add a minor threat: such predators as birds, spiders and mantises.
Monarchs in western North America overwinter in coastal California (roosting in eucalyptus, Monterey pines, and Monterey cypresses), while those in eastern North America "have a second home in the Sierra Madre Mountains of Mexico" (roosting in oyamel fir forests), as noted by the U.S. Forest Service.
"Researchers are still investigating what directional aids monarchs use to find their overwintering location," the U.S. Forest Service says. "It appears to be a combination of directional aids such as the magnetic pull of the earth and the position of the sun among others, not one in particular."
We're glad to see that the raging controversy over native vs. non-native milkweed is subsiding a bit, as the more crucial threats are pesticides, habitat loss, and climate change. After all, tropical milkweed, a native of Mexico, has been in California for more than 100 years. And longer than that when you consider that California was once part of Mexico. A. curassavica is also native to Central America (including Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama) and South America (including Colombia, Ecuador, Peru, and Venezuela), according to Johnny Butterflyseed.

Informational Videos Covering Fertilizer Application through Irrigation Water
Now Available in English and Spanish
Nicole Nunes FREP Grant Program
Through a grant from the Fertilizer Research and Education Program (FREP), Cal Poly's Irrigation Training and Research Center (ITRC) has developed a series of informational videos covering chemicals, application hardware, techniques, and timing of fertilizer application through irrigation water.
The videos are based on information provided in the Fertigation book developed by ITRC and updated in 2019. The Fertigation book is also available in English and Spanish and can be downloaded for free from the ITRC website: https://www.itrc.org/books/index.html
The 22 informational videos are available on YouTube or through the ITRC website and cover the following topics:
- Overview
- Basic Fertilizer Chemistry and Vocabulary
- Nitrogen and the Environment
- Basic Soil Principles
- Crop Fertilizer Requirements
- Testing of Plants Soil and Water
- Fertilizer Labels Characteristics and Usage
- Nitrogen Conversions
- Volatilization of Ammonia from Irrigation Water
- Irrigation System Uniformity and Efficiency
- Safety
- Purging Media Tanks of Chemicals
- Calibration, Titration, and Travel Time
- Varying Venturi Injection Rates
- Chemigation for Soil Infiltration Problems
- SO2 Generators (Sulfur Burners)
- Chemigation for Drip System Maintenance
- Incompatibility of Different Fertilizers
- Proportional Injection
- Fertilizer and Chemical Injection Devices
- Calibration of Fertilizer and Chemical Injectors
More Fertigation Resources Coming Soon
ITRC is developing the informational video series into a Fertigation Certificate Program available to the irrigation and fertilizer industry. The videos will be coupled with information and suggested readings from the Fertigation book to create a comprehensive online course. Course participation will be verified with an exam on the presented materials and successful participants will receive a certificate of completion.
Stay tuned for more information regarding the availability of the certification program.

So, here you are, a newly eclosed Western tiger swallowtail, Papilio rutulus, eager to sip some nectar from a Mexican sunflower, Tithonia rotundifola, in a Vacaville garden.
It's a warm, windless day, and you're anxious to score, score, score.
You touch down on a Tithonia, but something whizzes by your tails.
Whoa! What was that?
You're startled, alarmed, and irritated. It's a territorial male long-horned bee, probably a Melissodes agilis. He aims to dislodge you from your blossom in his attempt to save the nectar for his would-be girlfriends.
You teeter, then totter, then take off. You touch down on another Tithonia.
Hey! Bee brain! Quit targeting me? Go away!
You head for another blossom, determined to grab a least "a little" nectar.
Stop it! Leave me alone! Go take a vacation!
But the bee isn't about to take a vacation. And he won't allow your "staycation."
Spoiler alert: The butterfly admits defeat and departs the flower garden, exasperated but with tails intact. The bee emerges victorious, its real estate intact.
Score: Bee, 3, Butterfly, 0.
The turf battle is over for today. Tomorrow? That's another day and another battle.
