Spotted Wing Drosophila in Raspberries

I received a report of "white worms" in fall-bearing raspberries associated with the activity of the non-native invasive pest, Spotted Wing Drosophila (Drosophila suzukii).  Spotted Wing Drosophila (SWD) is a tiny fly, nearly indistinguishable from our native common vinegar flies (also called fruit flies) without a magnifying device.

Banded Garden Spider

The banded garden spider (Argiope trifasciata) is found throughout Ohio; however, it may be easily overlooked in favor of its slightly larger and more stunningly colored cousin; the yellow garden spider (A. aurantia).

Woolly Bears on the Move boggs.47 Mon, 09/26/2016 - 14:38
Bristly "woolly bear" caterpillars have started their annual crawl-about in search of sheltered locations where they will spend the winter.  They may be found on sidewalks and walking trails or on the walls of homes and buildings.  Some may be slowly making their way to Vermillion, Ohio, to attend an annual festival held in their honor.

Goldenrod (Solidago spp.) is in full bloom throughout the state.  Soldier beetles (Chauliognathus pennsylvanicus, family Cantharidae) and locust borer adults (Megacyllene robiniae, family Cerambycidae) are commonly found on the flowers of this beautiful native plant adding to the plant's interest to entomophiles.

Orange Dogs and Family Matters boggs.47 Sun, 09/25/2016 - 18:36

I recently came across a bizarre looking caterpillar - it looked like bird poo - while looking on a wafer ash (Ptelea trifoliate) for the white, frothy "egg plugs" of the two-marked treehopper (Enchenopa binotata) and admiring some heavy potato leafhopper (Empoasca fabae) damage.  I learned the bizarre looking caterpillar has an appropriately bizarre sounding common name:  the orange dog.

 

The orange dog (sometimes called orange puppy) caterpillar is the larval stage of the eastern giant swallowtail butterfly (Papilio cresphontes).  As...

Wafer ash (Ptelea trifoliate) which is also known as common hoptree or stinking ash has garnered considerable landscape interest in recent years owing to its native status in Ohio. However, wafer ash is also a potato leafhopper (Empoasca fabae) magnate.

A Very Unusual Leaf Gall boggs.47 Mon, 09/19/2016 - 16:52
A number of interesting plant galls look so much like fungal structures that for years they were misidentified as a fungal plant disease.  Such is the case with the goldenrod leaf galls associated with the midge fly, Asteromyia carbonifera.
