Some plants and pollinators have unique relationships. Take the rush milkweed.
Most years our rush milkweed plants only produce one or two seed pods each.
This year, however, the plants are covered with seed pods.
Why?
To figure out, we need to go back a few weeks. At that time the plants were covered with flowers.
We also saw a lot of tarantula hawk wasps visiting the flowers.
Although they are clumsy giants, tarantula hawks are especially good at pollinating milkweeds. Their long legs slide into the grooves in the flowers, where they collect the sticky sacs of pollen called pollinia (for more information, see BugGuide). When the wasps visit the next flower, the process is reversed, leaving the pollinia behind to pollinate the plant.
This year the tarantula hawk wasps were abundant and now the seed pods are, too, which hopefully means
soon we’ll see more milkweed seeds,
which will glide away on their silky parachutes to make more rush milkweed plants, which are
good for the monarch caterpillars that eat them, and
which turn into monarch butterflies, important pollinators for many other wildflowers.
All thanks to tarantula hawks!
Dragonflies are fun to watch because they often return to the same perch over and over, giving you the opportunity to observe them closely.
Watch the abdomen on this one.
It has tipped its abdomen up into what is called the “obelisk posture.”
