An Ode to Catalpas … Their Hornworms and a Tiny Wasp.

Northern Catalpa (Catalpa speciosa, family Bignoniaceae) trees are in full-bloom in southern Ohio. Last year, I posted a BYGL Alert! extolling the virtues of catalpa trees; both northern and its southern cousin (C. bignonioides). Of course, I recognized a few minor shortcomings, but no tree is perfect. I noted that whether viewed as a beautiful, resilient native tree that will compliment any urban landscaping, or a coarse, messy, tree best confined to forested bottomlands, no one can ignore the beautiful bell-shaped blooms!

Hail to Trails

This is a byglbook-alert, premature since I have only read the first chapter of the featured book, but I have started down its path of poesy and prose and hope you will too. The book is On Trails by Robert Moor (not “Moop”, for George Costanza fans).

 

  Robert Moor set out to hike the Appalachian Trail, Georgia to Maine, in 2009.  He speaks of this and then from there starts to muse deeply on the idea of trails, of paths, in his words “a meditation upon trails.”

Fire Walk With Carrie

Is this a cross between the weird David Lynch genre and early Stephen King horror?  No. I was meeting with an arborist extraordinaire earlier today and when we exhausted our arboricultural topics she showed me a picture of what she purported to be, scarlet campion.

 

  I thought not – and for once was right – it was fire pink, Silene virginica.  She encountered this great woodland wildflower with her husband Bill at Lake Hope State Park in southeast Ohio on Mother’s Day. It is unusual to see such brilliant red color in the spring and summer woods.

Tree of the Week: Bladdernut

Now we turn to a second plant identification discussion from arborist Carrie Paulus: this one of a native small tree or large shrub.  The above photograph is credited to Carrie.  She saw this small tree with husband Bill at Lake Hope State Park on Mother’s Day.  It is bladdernut, Staphylea trifolia.  It is not rare in Ohio woodlands, but often it is not noticed.

 

  Bladdernut eludes the usual mnemonics for native woodland trees with opposite leaf arrangement such as MAD BUCK (maple, ash, dogwood, buckeye) or BAMEV DOGWOOD (same along with tree-sized euonymus and...

Poison hemlock (Conium maculatum) is one of the most lethal plants found in North America. This biennial weed is now producing flowers in southwest Ohio. So, the clock is ticking on preventing seed production by this non-native invasive plant.

Hawthorn Leafminers Have Completed Their Development in S.W. Ohio

On April 11, I reported that the adults of three leafmining sawflies were mating and laying eggs on their host trees in southwest Ohio (see BYGL Alert! Sawfly Leafminers Fly). Today, I noticed some heavy leafmining damage by one of the sawflies, the Hawthorn Leafminer (Profenusa canadensis), on its namesake host in a hospital parking lot in the southwest part of the state.
