Even though temperatures here in Florida are still quite warm, they are beginning to cool off and the days are definitely getting noticeably shorter. These are the first signs that fall is on its way, and the wildlife is starting to get ready for winter. This not only includes vertebrates, but this preparation is essential to survival of most insect species, too. Butterflies are mating and laying eggs, longer lived insects are fattening up for a their hibernation period, and solitary wasps, like this mason wasp (Pseudodynerus quadrisectus) are building and supplying their intricate nests with food for the larvae. This particular wasp was in the process of getting a drink of nectar when this photo was taken, but it had also been flying around between other plants, gathering and chewing up plant fibers that it will use to build its nest. Once the nest is complete, it will paralyze and capture caterpillars that will feed the larvae in the spring. Finally, it will lay eggs in the nest before it dies. The eggs will lie dormant throughout the winter before hatching as the temperatures rise. It’s interesting and a bit sad watching these insects working to insure the survival of their genes as they begin the last weeks of their lives.
