Papilio polytes, commonly known as the Common Mormon, is a species of swallowtail butterfly widely distributed across Asia. This butterfly is renowned for the mimicry displayed by its numerous forms. The caterpillars of the Common Mormon can negatively impact crop yields. Interestingly, these caterpillars resemble bird droppings while resting on leaves, which helps them avoid predators. However, they are heavily parasitized by chalcidoid wasps, with over a hundred tiny wasps eventually emerging from each pupa. On September 4, 2024, in Tehatta, West Bengal, India, a tiny Common Mormon caterpillar was observed feeding on plant leaves, nearly camouflaged as it blended with the branches.

Sceliphron, also known as black mud daubers or black mud-dauber wasps, is a genus of Hymenoptera of the Sphecidae family of wasps. They are solitary mud daubers and are building nests made of mud. Nests are frequently being constructed in shaded niches, often just inside windows or vent openings, and it may take a female only a day to construct a cell requiring dozens of trips carrying mud. Females of some species are laying a modest average of 15 eggs over their whole lifespan. Various parasites are attacking these nests, including several species of cuckoo wasps, primarily by sneaking into the nest while the resident mud dauber is out foraging. Like other solitary wasps, Sceliphron species are not being aggressive unless threatened. They are sometimes being regarded as beneficial due to their control of spider populations. This photo was taken in Tehatta, West Bengal, India, on June 24, 2024.
