This little inch worm is either very smart or very stupid. On the blooms to Rattlesnake Master is about the last place I'd expect to find a caterpillar. I've seen nothing but assorted wasps pollinating that plant.
At least two are species of Scoliid wasp. This plant is beneficial in how many specialized predatory wasps it attracts alone.
Here's part 3 of the videos I've been doing. Wasps are very easily spooked. So often I'll go out to film the wasps only have have half of them fly off the plant. This time though they were all fairly well behaved.
