Poison hemlock (Conium maculatum) and wild parsnip (Pastinaca sativa) are two of our nastiest non-native weeds found in Ohio. Poison hemlock is one of the deadliest plants in North America. Wild parsnip can produce severe, painful blistering. Both are commonly found growing together.

Four-Lined Plant Bugs (Poecilocapsus lineatus, family Hemiptera) are one of the sneakiest, quickest hitting spring pests found in Ohio. Hordes of hungry bugs descend seemingly out of nowhere to cause extensive leaf damage, then they just fade away leaving behind their foliar wreckage.

Have you seen this flowering plant?  Don't be fooled by the beauty of Dame's rocket...

I've posted a number of BYGL reports over the past several years of a leafminer on wild buckeyes (Aesculus spp.). I first ran across the leafminer in a park near my home in Butler County, OH. However, the culprit was unknown; it had never been classified by science.

What began in 1950 as a young sapling, Camp Canopy (formerly known as Ohio Forestry & Wildlife Conservation Camp) has grown into a mighty oak as one of the most popular summer camps among high schoolers in Ohio, hosting 10,000+ campers since its inception. Many students have taken what they learned during their summer(s) spent at Camp Canopy and have gone on to study natural resource disciplines at their post-secondary institutions. Others have simply learned a ton of cool stuff related to forestry and wildlife in Ohio. Either way, Camp Canopy’s legacy will live on in generations of...

I identified the culprit behind the elm sack galls pictured in the BYGL Alert posted yesterday as the aphid, Tetraneura ulmi. However, thanks to input from Dan Potter (University of Kentucky, Entomology), I learned that the true identity is actually another closely related elm gall-making aphid, T. nigriabdominalis.

White fringetree (Chionanthus virginicus) is a lovely May addition to native landscapes with attractive foliage, elegant frilly flowers, and blue drupe fruits.

On Fridays, the OSU Turfgrass Team records their timely Turfgrass Times. Early in the season, the group recorded these video updates every other week, but as we are into the season, expect these turfgrass updates on a weekly basis. Team regulars included Dr. Karl Danneberger; Dr. David Gardner; Dr. Ed Nangle; Joe Rimelspach; Dr. Zane Raudenbush; Dr. Pamela Sherratt; and Dr. Dave Shetlar (aka the Bug Doc); and occassional special guests.
