Something Blue

One of the most striking plants in our prairies this time of year is pitcher sage, also known as blue sage (Salvia azurea).  It’s tall, of course, but more importantly, as the surrounding prairie is dominated by green-becoming-gold grasses and big yellow flowers, pitcher sage stands out simply because it is starkly and unabashedly blue.

A few weeks ago, I posted a photo of a bee that specializes on pitcher sage, but there are many more insects commonly seen on the plant.  Last week, I spent about 45 minutes in our Platte River Prairies, photographing pitcher sage and as many visitors as I could.

I initially pulled my camera out because there were several monarch butterflies flitting around a patch of pitcher sage.  While chasing them around (and, as always, being thankful no one was watching me), I came across quite a few other insects – some of which I managed to photograph.

A sulphur butterfly (and a second partially shown at the bottom left) enjoys pitcher sage.

Anthophora walshii (a digger bee) is a species I see on pitcher sage frequently, and this was just one of several hanging around a single patch of flowers.

This moth was nose deep.

Several skipper butterflies were around, including this sachem skipper.

Not all the insects were feeding on pollen and nectar.  I’m not sure what this plant bug was doing, but there it was.

This blister beetle was feeding on the flower itself.

This monarch was so distracted by the nectar of pitcher sage, I took this photo from about a foot away with a wide angle lens.

One more monarch…

In addition to being tall, striking, and beautiful, pitcher sage is also pretty good at withstanding drought.  During late August of 2012 – a year of extreme drought, pitcher sage stood out against a background of brown dormant grass, blooming just like it does every year.  Not only did it provide some welcome color when many other plants were wilting, it gave all the insects pictured above, and many others, something to eat when they needed it most.

What a great plant!

Predators play key roles in ecosystems.  When they are absent or rare, impacts ripple through landscapes, often in unexpected ways.  We all rely on the presence and effectiveness of predators, but usually fail to adequately celebrate their importance.

When thinking about predators, most people probably conjure up images of lions, tigers, bears, and other large vertebrates.  However, smaller invertebrate predators play the same kinds of critical roles as those big animals.  Here are a few portraits of tiny predators that help keep prairies healthy and vibrant.

No one will be surprised that I included a crab spider in this batch of images. This one ambushed a hover fly on hoary vervain (Verbena stricta).

This juvenile assassin bug is finishing off a fly.

This adult assassin bug sits poised and ready to attack any prey that comes near.

Jumping spiders, the teddy bears of spiders, are very effective predators – maybe because their prey gets distracted by their cuteness.

Dragonflies are large nimble predators that (fortunately for us) are big enough to handle small insects, but not big enough to cause us harm.
