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.
A syrphid fly using its proboscis to reach the nectar of a flower. 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. In vertebrates, a proboscis is an ...
In bees, the maxillae and labium have been modified and fused to form a nectar-sucking proboscis. In the order Hemiptera, the true bugs, plant hoppers, etc., the mouthparts have been modified to form a beak for piercing. The labium forms a sheath around a set of stylets that consist of an outer pair of mandibles and an inner pair of maxillae.
In the honey bee (Hymenoptera: Apidae: Apis mellifera), the elongated and fused labial glossae form a hairy tongue, which is surrounded by the maxillary galeae and the labial palps to form a tubular proboscis containing a food canal. In feeding, the tongue is dipped into the nectar or honey, which adheres to the hairs, and then is retracted so ...
The shape and dimensions of the proboscis have evolved to give different species a wider and, therefore, more advantageous diet. [3] There is an allometric scaling relationship between body mass of Lepidoptera and length of proboscis [22] from which an interesting adaptive departure is the unusually long-tongued sphinx moth Xanthopan morganii ...
What is unusual is that many Hymenoptera have the remaining mouthparts modified to form a proboscis (a "tongue" used to feed on liquids), making them virtually the only insects that normally possess both chewing mouthparts and sucking mouthparts (a few exceptional members of other orders may exhibit this, such as flower-feeding beetles that ...
Dorothea Puente, perhaps Sacramento’s most notorious murderer, was so seemingly non-threatening that authorities let her out of their sights time and time again — even after digging up seven ...
The collective term for the segments between the club and the antennal base is the funicle; traditionally in describing beetle anatomy, the term "funicle" refers to the segments between the club and the scape. However, traditionally in working on wasps the funicle is taken to comprise the segments between the club and the pedicel. [10]
