Gallignostics

  Let us call this A Case of Gallignostics. Plant galls are defined as abnormal plant growths caused by a gall-maker; the gall-maker being certain insects, mites, fungi, and bacteria. From horned oak gall to bacterial crown gall, from maple bladder galls to cedar-apple rust galls, there are many galls of interest to horticulturists. Relative to all this, Joe Boggs recently got an e-mail from Michael Goldman of the Grange Insurance Audubon Center:

A Stinging Commentary on Wasps, Yellowjackets, and Baldfaced Hornets.

Paper Wasps, Yellowjackets, and Baldfaced Hornets are beneficial insects. Just keep repeating that to yourself when you're being chased or stung by these hymenopteran marauders!

Look closely at the leaves of ornamental sweet potatoes, morning glories, or bindweed for flecks of gold creeping across the lower leaf surfaces; those would be Golden Tortoise Beetles (Charidotella sexpunctata).

Trefoil Foiling Lawns, Landscapes, and Naturalized Areas

The bright yellow floral display currently blanketing some lawns and roadway right-of-ways is being produced by Birdsfoot Trefoil. The yellow flowers are smaller than dandelion flowers, bigger than those of black medic, and resemble buttercups from a distance.

Yet another example of unintended consequences with introducing non-natives.
