n Sticky bedstraw (Galium aparine) has been the star of the garden in terms of weeds. It appears to be showing in every single place this 12 months, even in beds the place it was not final 12 months.

Sticky bedstraw is a winter or spring herbaceous annual. It will possibly germinate late summer season into fall and places on a number of inches of development earlier than winter.

Come spring it is able to leap into weedy motion, shortly outgrowing surrounding vegetation. It will possibly simply develop 3 ft lengthy or extra and engulf a plant with its sticky stems and leaves.

Bedstraw usually kinds dense, tangled mats that sprawl on the bottom or over neighboring vegetation.

These are all indicators of two widespread bugs — Tarnished Plant Bug (Lygus lineolaris) and the 4-Lined Plant Bug (Poecilocapsus lineatus).

Each are members of the Hemiptera order of bugs and feed on all kinds of vegetation. They feed by inserting their piercing-sucking mouthparts into plant tissue and sucking out the sap.

It’s thought that additionally they inject a poisonous substance — probably digestive enzymes — into the plant when feeding which breaks down plant tissues.

Tarnished plant bug adults are about 1/4 inch lengthy, oval formed, bronze to darkish brown, with white marks behind the pinnacle and generally alongside the entrance wing. The immature stage, or nymph, is wingless, and they’re often inexperienced, whereas some youthful ones might be yellowish.

The Asian big hornet (Vespa mandarinia), first detected within the Pacific Northwest in 2019, has not been discovered on the East Coast. Nevertheless, European hornets are effectively established within the space.

Queens can attain 1.3 inches and are reasonably intimidating. The top is purple and yellow, and the thorax (center area) is purple and brown.

The stomach has two massive brown sections by the waist and a largely yellow posterior with brown tear-drop markings.

European hornets construct annual nests, often in hole timber or probably a wall void. Solely fertilized queens survive the winter to start out a brand new colony the following 12 months.

Queen hornets want a protected place to over winter and in the event that they occur to do this in your attic, they could discover their method into your own home within the spring once they get up.
