I used to think the bagworms used threads as safety lines when they jump out of trees to avoid ant predators. While this is true, I have noticed lately that the biggest ones have been hanging on long threads for hours and I think they use the weight to spin super strong threads in preparation for pupating into moths over the winter. They use their front six legs to gather up the extruded thread and make a fuzzy pad to affix their bag to a solid surface, often a gate, or fence post.
The high winds brought down a sunflower stalk and the insects associated with it. Pocket gophers will bring down the stalks by eating the underground roots, but in this case the culprits was a nest of jeweled bugs, or figeaters. They make a loud buzzing and most people mistake them for wasps or bumblebees. They chew through the stalks of sunflowers to suck the sweet sap under the surface. Often other insects are attracted to the injury too.
There are definitely signs of the coming fall in the air, right now. The bagworms are getting bigger, there are many birds moving into the bosque, like flocks of geese, ducks, vultures and crows. Many are attracted to new food sources, like fallen apples in the orchards. The mammals are also interested as the ditches are less used and the isolated pools are holding trapped fish and other foods. A specialist predator of fish and tadpoles are the harmless garter snakes, they should be a lot more visible as summer begins to wind down.
I like all of the pictures and the format here. Beware of forest pixies!
