Aburame clan is different. They form a contract with the bugs when they are born so that the bugs will feed off the host's chakra in exchange for control over the bugs. And the only actual jutsu they use is the one where shino uses the jutsu to draw out bugs.
Bug clones.
Bug shield.
That new bug thing he used in the last chapter.
Chakra drain.
Miha:I'm quite sure someone with your imagination, should be able to figure out that putting forming bugs into a shield or clone is more of bug manipulation than a jutsu. Mushi Dama makes the bug surround the opponent in a sphere like fashin then collapse in and feed off the opponent's chakra. Does that sound like a jutsu?
Tau:(wikipedia) The Destruction Bug Host Technique (寄壊蟲の術, Kikaichū no Jutsu?, English TV "Parasitic Insects Jutsu") is a symbol of membership to the Aburame clan. When a child is born into the Aburame family, their body is offered to insects as a nest. The bugs feed and live off the chakra that the body stores and in return the ninja gets to control and command the bugs, using them as their primary fighting technique. These bugs have the ability to drain chakra through physical contact with the enemy.
Regardless i see no handsigns >.>
