Proboscis - Wikipedia
A proboscis (/ p r oʊ ˈ b ɒ s ɪ s,-k ɪ s /) is an elongated appendage from the head of an animal, either a vertebrate or an invertebrate. In invertebrates, the term usually refers to tubular mouthparts used for feeding and sucking.
Insect mouthparts - Wikipedia
The proboscis, as seen in adult Lepidoptera, is one of the defining characteristics of the morphology of the order; it is a long tube formed by the paired galeae of the maxillae. Unlike sucking organs in other orders of insects, the Lepidopteran proboscis can coil up so completely that it can fit under the head when not in use.
Feeding Mechanisms of Adult Lepidoptera: Structure, Function, …
Compared with the proboscis of other nectarfeeding insects, the proboscis of Lepidoptera has several unique features. It forms a flat, vertical spiral when at rest (Figure 2a), it consists of merely two components, and it functions primarily by means of a hydraulic mechanism .

The mouthparts of a female mosquito are highly modified to form a proboscis that is adapted for piercing skin and sucking blood. Males have similar mouthparts, but they feed only on nectar. The proboscis is similar to a sword within a scabbard. The mosquito’s labium is the scabbard (sheath).

'Butterfly Tongues' Are More Ancient Than Flowers, Fossil Study Finds - NPR
Jan 10, 2018 · Scientists have discovered the proboscis butterflies use to suck nectar from flowers existed before flowers did. So: What were ancient butterflies using their long, tongue-like suckers for?
