What are the characteristics of a hemipteran?
Hemipteran mouthparts are distinctive, with mandibles and maxillae modified to form a piercing “stylet” sheathed within a modified labium. The defining feature of hemipterans is their “beak” in which the modified mandibles and maxillae form a “stylet” which is sheathed within a modified labium.

What is the difference between the Hemiptera and Phthiraptera?
Although the Hemiptera vary widely in their overall form, their mouthparts form a distinctive “rostrum”. Other insect orders with mouthparts modified into anything like the rostrum and stylets of the Hemiptera include some Phthiraptera, but for other reasons they generally are easy to recognize as non-hemipteran.
