Our resident crab spider, family Thomisidae, appears to be an extremely poor hunter. She waits, camouflaged in the lavender patch, as bees buzz around her. They dart away when she lunges at them.
So here I am, a crab spider, as hungry as can be
Does anyone out there feel sorry for me?
"Yes," say the arachnologists. The apiculturists say "no."
Well, I'll just hang out in the lavender and keep lying low.
Hey, looky there! I'm going to fast-track that bee.
Sorry, I am who I am, and...

Blister beetles (family Meloidae) are so named because they emit a poisonous chemical, cantharidin, that can blister your skin. Don't even think about touching them!
Blister beetles can infest alfalfa hay, and are toxic--even deadly--to livestock. See "Blister Beetles" published by the Montana Agricultural Experiment Station.
But did you know that...
Blister beetles are pollinators!
We recently saw a blister beetle eating pollen on a Mexican sunflower, Tithonia rotundifola. We've also seen this insect transferring pollen.
But we have...

How policies affect emissions, land use, and the prices of fuel and vegetable oils
Over the last two decades, both the federal government and state governments have enacted policies to reduce greenhouse gas (GHG) emissions in the transportation sector. In a new Special Issue of ARE Update, University of California agricultural economists explore how these federal and state renewable fuel policies have affected biofuel production for motor and aviation fuels and consider how these policies have affected land use and food prices. Their research shows that as U.S. demand for...
