What's Noshing At Clay and Limestone

Pennsylvania Leatherwing on Sneezeweed/Helenium autumnale
I've a new critter in the garden~This is the first Clay and Limestone  sighting for this super duper cool Halloween colored soldier beetle.  Am I ever glad I checked this critter out before dispatching it to bug Hades.   Pennsylvania Leatherwings are highly desirable  biological control agents.  Simply stated~they are good bugs that eat bad bugs!

A highly beneficial rascal to have around the garden.
Don't you think it resembles a Lightening Bug (LB)?  I did, and that helped me discover  its identity.  Describing what it looked like and  on which flowers it was feeding  took me almost immediately to Pennsylvania Leatherwings. What a cool critter.   It's no accident that the PLB resembles its close relative the firefly/Lightening Bug.  Clever Mother Nature helps critters mimic poisonous look-a-likes and survive  predators.  No smart bird or wasp wants to eat anything that resembles a  firefly with their poisonous blood that oozes from the base of their wing covers.   On the other hand~our orange hero is a tasty treat  for birds, bats, spiders, ground beetles, and other small predators.

Soldier Beetles and Green Metallic Bee on Verbisina virginica
 Prof Michael Raupp wrote that,  "Like other members of this clan, soldier beetles are natural born killers in both adult and juvenile stages and are highly beneficial rascals to have around the garden." (source) The adult Pennsylvania Leatherwings are especially important predators of aphids and their larva consumes grasshopper eggs, aphids, small beetles, caterpillars and other soft bodied insects, most of which are pests.  Go here  and here for more on their life cycle.  I sure hope they lay eggs in the soil in my garden~I've had a plague of  grasshoppers this year,  so there will be lots of their eggs  for them to nosh on!

A pest consuming machine

The Pennsylvania Leatherwing may be a  pest consuming machine but, they play an important role in pollinating native plants like  Helenium autumnale/Sneezeweed,  Verbesina virginica/Frostweed  and other native plants in  natural areas and our gardens.
They supplement their diet with pollen and nectar
I am tickled pink to find these beneficial insects living in the garden and dining on the natives that were added to the menu with this in mind. Later this month when the Goldenrod Blooms they may stop by to nosh on its golden  pollen.  When that happens I'll call them by their other common name: Goldenrod Soldier Beetle.

They're also  Very Important Pollinators
What's noshing in your garden?
