A heavily infestated host plant (Breynia androgyna, commonly known as Sweet Leaf Bush).

As stated in the Plant Pest Factsheet by the Department of Environment Food and Rural Affairs in the United Kingdom, the eggs are consistently laid in partial circles and have a greyish hue. Another possible candidate for this whitefly species is Bemisia tabaci (commonly known as Silverleaf Whitefly or Sweet Potato Whitefly), which may coexist with the Greenhouse Whitefly on the same host plant.
