In May 1889, Van Gogh began work on Green Peacock Moth which he self-titled Death's Head Moth.
The moth, called death's head, is a rarely seen nocturnal moth.
He described the large moth's colors "of amazing distinction, black, grey, cloudy white tinged with carmine or vaguely shading off into olive green".
Behind the moth is a background of Lords-and-Ladies.

The size of the moth and plants in the background pull the spectator into the work.
The colors are vivid, consistent with Van Gogh's passion and emotional intensity.
Van Gogh Museum's title for this work is Emperor Moth.
Vincent van Gogh | Poppies and Butterflies, 1889
When Van Gogh made Butterflies and Poppies he started with the flowers and butterflies and filled in the blue background only afterwards.
This is clear from the fact that the broad strokes of blue paint occasionally cover the green stems of the flowers.
Van Gogh even left part of the canvas unpainted, with the bare cloth visible.

Using various shades of green, he gave depth to the tangle of stems, leaves and petals. Van Gogh skilfully captured the spirit of the delicate poppies.
