Tithonia is also known as “Mexican Sunflower.”

This is a fun flower to photograph. Its color is vivid. The blooms appear on gracefully curved stems. It attracts a variety of pollinators. It does make a few seeds for the birds, but not in the same quantity as regular sunflowers.

This is my first bloom of tithonia this year.

Hover Fly Update

Hover Fly Update

Hover Fly update with commentary of Baldo Villegas, who is now retired but former State Entomologist for California. I had written him last week, but was not sure I had the correct email. Yesterday afternoon I received his response. As all of his responses, this one is full of information and also interesting and easy to understand. Baldo helps everyone! Thank you, Baldo!

The insect in the picture is a Syrphid fly, not a wasp but a mimic. These flies belong to the large family of flies called Syrphidae and are known by the common names Hover Flies or Flower Flies. Most have warning coloration resembling that of wasps or bees. In fact there is one species that is commonly called a drone fly as it looks just like a male honey bee. Most syrphid flies are predators of soft bodied insects such as aphids. A few are pests of bulbs and such and others have interesting lifecycles and are rather interesting.

Syrphid flies will visit flowers for nectar and pollen in order to help in egg production. The nectar is for the energy that they consume hovering around aphid infested plants.

Baldo’s tagline in his email is “Love Bugs, Roses and Cats …. even if the cats don’t give a hoot.” 🙂

This gives me a chance to repost the photo:

Pollen Wasp: No, Just a Hoverfly

Pollen wasp is something I had not known about until a few days ago. Yet, pollinators are something we talk about frequently, because of their vital importance to crops and virtually all plants on earth. I, and neighbors, try to include flowers that will attract pollinators. While we tend to think about the beauty of the the flowers, we talk less about the beauty of our pollinating friends. Yet, up close and personal, they can be beautiful and interesting.

Regular readers and friends know that I have grown a variety of sunflowers for years. Years ago in Arizona I grew Tithonia rotundiflora (“Mexican sunflower”). It is in the same Family, Asteraceae, as our typical sunflowers. However, the genus is Tithonia rather than Helianthus. When I saw seeds in the grocery store, I thought maybe it would be fun here. So, I decided to try it. It is a fabulous plant for Albuquerque!

The other day I was out photographing the flowers. I saw a wasp on the tithonia. While I considered it a yellow jacket, its behavior seemed odd for a wasp. It almost seemed to be making love to the flower. So I kept photographing it, hoping I could understand what was going on. When I looked at the images on the computer, I saw what appeared to be a very odd mouth part. As it turns out, it is a very specialized mouth part, a “suctorial proboscis.” (These wasps – this isn’t one) are solitary vegetarians, sucking nectar and pollen from flower tubules.) As it turns out, what I took to be a wasp is, in reality, a hoverfly with also very specialized suctorial proboscis. Example here: hoverfly

The joy of photography: seeing and learning new and different things, without even trying! Last week I did not know what a pollen wasp was. Now I know what it is, and this is not one. It is a hoverfly. Now I know they also have these very specialized suctorial probosci. This week I am glad this one chose to visit my garden and allowed me to photograph it! And thanks to Anita Storino for the updated information.
