Mylothris agathina, the eastern dotted border or common dotted border, is a butterfly of the family Pieridae. It is native to sub-Saharan Africa, particularly East Africa and southern Africa. In South Africa its range has spread westwards around the coast in the late 20th century, and it now occurs north of Cape Town to somewhat beyond Saldanha. [2]

Description

The common dotted border have bright white wings with shades of yellow, with black dots along the wing margins. The wingspan is 50–60 millimetres (2.0–2.4 in) for males and 52–65 mm (2.0–2.6 in) for females. The slow-flying adults are on wing year-round, with peaks in October and from late February to April. [3]

Habitat

Mylothris agathina is commonly found in sub-Saharan Africa, particularly in savannas, forests, grasslands, open woodlands and bushveld areas. They are often spotted in suburban gardens, especially at the top of trees. They prefer areas with abundant flowering plants and males often mudpuddle. ,They rely on nectar as a food source such as the Natal Blue Haze (Tetraselago natalensis), which is a great nectar plant found in the threatened grasslands of KwaZulu-Natal (KZN).

These grasslands are often located near forests, where the butterflies are commonly sighted. Additionally, Mylothris agathina larvae are known to utilize hemiparasitic plants such as Hairy Mistletoe (Erianthemum dregei) and African Sandalwood (Osyris lanceolata) as host plants.

Distribution

Sudan, Ethiopia, Somalia, Kenya (east of the Rift Valley), Tanzania, Democratic Republic of Congo (south), Angola, Malawi, Zambia, Mozambique, Zimbabwe, Botswana, Namibia, South Africa (Limpopo Province, Mpumalanga, North West Province, Gauteng, KwaZulu-Natal, Eastern Cape Province, Western Cape Province), Swaziland. [4]

Lifecycle

Lifecycle: The lifecycle of Mylothris agathina follows the typical stages of a butterfly: egg, larva (caterpillar), pupa (chrysalis), and adult. The eggs are typically laid on host plants such as Hairy Mistletoe and African Sandalwood, where the caterpillars hatch and feed. The pupae resemble bird droppings. [2] After undergoing metamorphosis, the adult butterflies emerge and begin searching for mates and food.

Diet

As caterpillars, Mylothris agathina larvae feed primarily on leaves of host plants within the family Fabaceae (legumes) such as Erianthemum dregei commonly known as Hairy Mistletoe and Osyris compressa (formerly Colpoon compressum) known as African Sandalwood. [5] The gregarious larvae feed on various host plants like Tapinanthus oleifolius , Tapinanthus rubromarginatus , , Teighemia quinquenervia , Ximenia caffra , Osyris lanceolata . [5] As adults, they primarily feed on the nectar of flowering plants, including Tetraselago natalensis , known as Natal Blue Haze and other flowering plants found in their habitat

Predation and Defense mechanism

Mylothris agathina faces predation from birds, reptiles, and insects.

Conservation

The conservation status of Mylothris agathina is currently not assessed on the IUCN Red List. However, like many butterfly species, they may be susceptible to habitat loss, climate change, and other environmental threats. Conservation efforts may include habitat preservation, restoration projects, and raising awareness about the importance of butterfly conservation.
