Two Spot swordtail butterflies (Graphium nomius) mud puddling for minerals. Nectar-feeding insects gain enough water from nectar to rarely need to drink, though adult butterflies and moths may engage in puddling in order to obtain dissolved substances not abundant in nectar, particularly salts and amino acids.

A Dryas iulia butterfly drinking from the tears of a turtle. Some Orthoptera – e.g. the yellow-spined bamboo locust (Ceracris kiangsu) – are attracted to human urine, specifically to the sodium and ammonium ions in it. [15] Those Lepidoptera that are attracted to dung (e.g. Zeuxidia spp.) or carrion seem to prefer ammonium ions rather than ...
Some caterpillars of Lycaenidae butterflies and some moths also produce honeydew. [2] In addition to various sugars, honeydew contains small amounts of amino acids, other organic compounds, and inorganic salts with its precise makeup affected by factors such as insect species, host plant species, and whether a symbiotic organism is present.

Nectar feeding birds typically have a mechanism to quickly excrete excess water. They may have to drink four to five times their body mass of liquid during the day to obtain enough energy. [26] Hummingbirds are capable of excreting nitrogenous wastes as ammonia since they can afford more water loss than birds that feed on low-moisture food sources.
In gardens, the presence of butterflies and hummingbirds is often encouraged. Butterflies are attracted by most good nectar sources, though there are particular plants they seem to prefer. Certain plants are also grown as a food source for their caterpillars. [6] Hummingbirds feed on tubular flowers, using their long, siphoning beaks. Many ...
The broad-billed hummingbird eats both nectar and insects. The hummingbird is also known to visit sugar-water hummingbird feeders. [18] Their eating habits showed that the broad-billed hummingbird prefers visiting red or red-and-yellow flowers the most. [8] To feed on nectar, the hummingbird will extend its bill and long tongue into the flower ...
Hummingbirds eat a lot—nearly half their body weight in nectar and bugs each day! But constant eating is what fuels them to keep their wings flapping up to 90 beats per second. You can help keep ...
