Overwintered fall webworm (Hyphantria cunea) eggs are hatching and first-generation nests are appearing in southwest Ohio. Look for these hairy caterpillars inside small silk nests enveloping just a few leaves. The nests will rapidly expand over the next few weeks to include more leaves and become more evident.

Calico scale (Eulecanium cerasorum) eggs located beneath helmet-shaped females are just about finished hatching in southwest Ohio. As soon as the 1st instar nymphs (crawlers) appear, they make their way to the undersides of leaves where they settle along leaf veins and use their piercing-sucking mouthparts to tap into the phloem vessels.

Overwintered common bagworm (Thyridopteryx ephemeraeformis) eggs are hatching in southwest Ohio. The 1st instar caterpillars are very small with their bags measuring around 1/8" in length.

During today's BYGL Zoom Inservice, Dave Gardner (Turfgrass Science, OSU Horticulture and Crop Science) showed pictures of Johnsongrass (Sorghum halepense, family Poaceae) springing up in turfgrass. The coarse bladed warm-season grass strongly resembles young corn plants and may present a weed identification challenge in turf.
