They are pointed not rounded. The hindwings are similar in colour and have a pale dot at the tornal margin. There are two generations per year with adults on wing from mid April to August.

Life Cycle of Marsh pug
Egg The embryonic marsh pug develops within an egg. The shell provides protection as the future larvae forms. The size is minuscule and the color usually blends with the environment to avoid predation.
Larva Emerging from the egg, the larva of marsh pug is mainly focused on feeding and growth. It has a worm-like appearance and periodically molts its skin as it increases in size.
Pupal The marsh pug enters the pupal stage encased within a protective cocoon. It is a transitional period where the larva undergoes significant internal changes, reshaping into the adult form.
Adult Emerging from the pupa, the adult marsh pug displays wings and functional reproductive organs. With a hardened exoskeleton, the creature is mobile and its primary function is now reproduction.

How Can You Attract Marsh pug
For adult marsh pug, light traps at night or pheromone traps can be used as they are attracted to lights and specific scents during the mating period.
Rectangle
Habitat Preferences of Marsh pug Through Different Life Stages
The eggs of marsh pug can often be found on the underside of the leaves of their host plants. Once hatched, the caterpillars prefer the tender leaves and are best searched for by examining the plant foliage they are known to consume. As they progress to pupation, look for them camouflaged in the detritus or bark of the host plant where they form their chrysalis. Finally, searching for the adult marsh pug would require night-time excursions near the host plants, as they are nocturnal and are attracted to light sources.

How and Where Can You Find Marsh pug at Different Life Stages
Egg Marsh pug eggs are often laid on host plants. Finding them involves careful inspection of the leaves and stems of potential host plants using a magnifying lens.
Larva Larval marsh pug can be found on host plant leaves where they feed. Look for signs of feeding damage or frass (insect excrement) on leaves, which can lead to discovery of the caterpillars.
Pupal Marsh pug pupae may be found in leaf litter or soil, or attached to leaves or branches. Gentle searching and turning over leaf litter or examining the crevices in bark can reveal their location.
Adult Adult marsh pug are nocturnal and are often found near light sources at night. A simple way to find them is to set up a light trap or go on a night walk near flowering plants.
