Butterweed / Cressleaf Groundsel: Beauty is in the Eye of the Beholder

The dichotomous nature of Butterweed may test the tolerance of lovers of native wildflowers. On one hand, a sea of yellow flowers carpeting farm fields flanking Ohio's interstates in the spring provides welcome relief from highway monotony. On the other hand, upright 2 – 3' tall plants bolting seemingly out of nowhere in Ohio landscapes presents a weed management challenge.

Look Up Before Parking Under Honeylocust Trees … and Elms, Hawthorns, Sweetgum, Zelkova …

We have a shopping center and hospital not far from my home in southwest Ohio that have parking lot tree planters with honeylocusts, lacebark elms, and a number of other types of trees. The trees provide shade, so they are car magnets. Unfortunately, a considerable number of the trees are heavily infested with Calico Scale.

Boxwoods Go Snap, Crackle, and Pop!

I've already posted a BYGL Alert on Boxwood Leafminer this season that described its life-cycle, detection, and management. However, I only briefly described one of the most notable side effects associated with this non-native midge fly: odd rustling or popping sounds radiating from heavily infested boxwoods.

Wilting Buckeyes

The handiwork of the Buckeye Petiole Borer is now becoming evident on its namesake host in southern Ohio. Individual caterpillars of this tiny native moth bore into leaf petioles to disrupt vascular flow causing leaves to droop, wilt, and turn dark green to black. Damaged leaves will eventually detach producing mild defoliation. Symptoms may superficially resemble frost or freeze damage.

Horned Oak Galls "Pop"

The physical emergence of the "horns" that give horned oak galls their common name is such a short-lived event I've only witnessed it one other time in 26 years. I've commonly observed fully extended horns, but seeing them in the process of breaking through the gall surface is a rare treat and it's happening right now in southwest Ohio.

Mining Bees on the Wing

There are many species of bees that create individual (solitary) burrows in the soil. Several hymenopteran families are represented including Andrenidae (Mining Bees), Apidae (Tribe Anthophorini (Digger Bees)), and Colletidae which are called cellophane bees owing to the waterproof plastic-like material they use to line their soil burrows. They all have one thing in common: they are important pollinators.
