Colourful butterflies congregate in large numbers in Kamloops and the Okanagan every summer as they engage in a natural phenomenon called mud puddling.
While most of a butterfly’s nutrition comes from sugary flower nectar, male butterflies need minerals and salts to enrich their sperm and breeding outcomes.
The males will gather around moist mud, dung and decaying flesh to drink and absorb salts and amino acids. Part of the nutrients are transferred to the female during mating and this extra nutrition helps the eggs survive, according to Earth Touch News Network.

Gardeners can attract mud-puddling butterflies by filling a shallow dish with soil or sand from the beach and pouring water over it make it moist. The addition of manure or compost and some overripe fruit helps attract butterflies, and a pinch of salt will ensure they get enough nutrients. The insects will need something to stand on as they can’t land on open water.
Area photographers were able to capture several species of mud-puddling butterflies at area lakes in the past few weeks, including a vary large congregation with two different species, and a closeup look of a butterfly with its proboscis in the soil.
