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. And a spiked foreleg that looks as if it's extending a hand in (fake) friendship. It's a praying mantis and it's staring right at you.
Such was the case recently when a female praying mantis, Mantis...

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.

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...

On Sept. 6, 2016, it happened.
A monarch fluttered into our pollinator garden in Vacaville and touched down on a Mexican sunflower, Tithonia rotundifola.
It wasn't just "any ol' monarch"--if there's ever such a thing as "any ol' monarch."
This one, tagged with my alma mater, Washington State University, came from Ashland, Ore., as part of a migratory monarch research project launched by entomologist David James.
The tag's serial number read “Monarch@wsu.edu A6093.” It hung around for about five hours and then left.
James, an associate professor at Washington State...
