Cluster-flies looking for hibernation sites in the windowframes.
Hop-dog caterpillar on Sorbus cashmiriana trunk in garden.
Several specimens of this plant have appeared in a weedy corner of my yard, adjacent to the tap where I clean the bird feeders. The associated species suggest that it was likely a contaminant in Niger seed, possibly having originated in Ethiopia.
The tallest of the plants is about knee-high. Leaves are opposite and nearly connate at base. Both leaves and stems are sticky-hairy and have lots of tiny dead flies stuck to them. The plant is also unpleasantly scented. None of the plants are showing any sign of producing flowers yet.
Any help identifying would be much appreciated.
