Scouting For Viburnum Leaf Beetle

The viburnum leaf beetle (VLB) (Pyrrhalta viburni) is a non-native invasive species that is making Ohio its home - well at least some of the buckeye state.  While the insect has been detected and is known to be in the northern portion of the state, we are encouraging all Ohioans to monitor for the pest and become aware of signs and symptoms if you aren't familiar with exotic invader. 

 

Last week, Mary Visco, horticulturist with the Toledo Botanical Garden (TBG) in Toledo, Ohio was scouting the viburnums in the Garden and noticed first instar larvae had hatched and...

Gnarled Oak Leaf Midge Galls

I've recently gotten e-mail messages with images of a gnarly looking leaf gall appearing on pin oaks in Cincinnati, OH, and Lexington, KY. The unsightly, lumpy growths are produced by a gnat-like gall-midge (Macrodiplosis niveipila, family Cecidomyiidae) and have the descriptive common name of Gnarled Oak Leaf Midge Galls.

A Nostoc Tour de Force

Our warm, wet spring has provided ideal conditions for the rise of a strange looking organism with a scientific name that sounds like a '70s California happening: Nostoc commune. This bizarre organism may look as if an agglomeration of rubbery yellowish-green to bluish-black material is "bubbling-up" in the open spaces in Ohio landscapes as well as gravel driveways.

Flower Celebration

  A lovely tradition of celebrating diversity (Oslava Květin) was started by Norbert Čapek, a Czech Unitarian, in 1923, with flowers as symbols of the universality of nature and ecumenical love. Start your own flower celebration in your home, for every business meeting, with your customers, sharing the beauty of flowers – especially this time of year: this “lusty month of May” (from Camelot). Everyone bring a flower! Here are a few floral fineries from my home and neighbors.

Holey Oak Leaves!

Look closely at developing oak leaves for Spiny Oak Sawfly (Periclista albicollis) larvae. The small, light-green, semi-transparent larvae have shiny black head capsules and are covered with rows of forked (bifurcated) spines. Their small size coupled with their coloration allows these larvae to easily blend with their leaf-food background.

Please Report Early-Bird Periodical Cicadas

Periodical Cicadas (Magicicada spp.) take either 17 or 13 years to complete their development and emerge from the soil en masse as different "broods" in the spring. The only periodical cicada brood that's forecast to emerge this year is Brood VI. However, there is a prediction that we will see an "early emergence" of some members of Brood X this spring even though adults of this brood are not expected to emerge full-force until 2021.

Badaling, Badaling: The Great Wall of China

A trip to China often includes a visit to The Great Wall of China, to some part of the 5500 to 13,000 mile collection of fortifications (depending on whether various branches are included).   So, I set out for the Great Wall with my guide Nina during my trip to the Beijing Botanic Gardens for their Crabapple Conference. Nina gassed up a Hyundai and we headed 50 miles northwest and over a half mile in elevation to Badaling (八达岭), the most visited section of the Wall and the first opened to tourists in 1957. From Nixon to Obama, to Nina and me.
