Smooth Sumac, Rhus glabra, is just beginning to bloom. I have an abundance of this plant along the
trail leading up the hill behind the house.
It gets mowed about every three years and blooms heavily the second year
after mowing. The result is a massive
display of blooms at just about eye level.
It’s just perfect for viewing visiting insects.
A flower head forms at the end of each branch. Smooth Sumac is a common species that is
recognized by its hairless stems.
The buzz of nectar eaters never ceases. Bees, wasps, flies and beetles are frequent
visitors of these flowers. Hairstreak
butterflies also make use of this nectar, but I have yet to see any of the
hairstreak species this year.
Tachinid Flies were the noisiest of the various
visitors. Tachinids come in a variety of
sizes and colors, but my preference is for these large types.
Tachinid larvae develop inside a living host, usually a
specific insect species. The adult flies
are so numerous it’s almost impossible not to see them when you’re in the
field. Despite seeing thousands of
adults, I’ve never seen a host insect containing a Tachinid larva.
This is a Yellow-collared Scape Moth. I see this day flier on many different flower
species that produce large flower heads.
The moth tends to take advantage of the flower cluster to partially hide
itself while feeding.
Beetles abound in the flower cluster. Most try to remain hidden among the small
flowers.
I think this is some type of Soft Winged Flower Beetle. I couldn’t tell if it was actually feeding
inside the flower or searching for something on the outside.
Of course the little green bees were there. I have yet to find a flower that doesn’t
attract these bees.
I think sumacs are one of the preferred flowers of Bumblebees. I always find an abundance of Bumblebees on
these blooms. I like to watch flowers
because of the wide assortment of insects that they attract. When they are busy feeding, insects are easy
to approach and observe. I’ll be
spending a lot of time around the sumacs for the next week or so in hopes of
seeing something new and unusual.
The variety of insects on one type of plant is amazing. Your posts provide a good reminder to look at everything more closely so as not to miss some of the smallest wonders of nature.
