The locusts got sucked in by the twister that is Adrian and started dying as soon as they are caught. The locusts were only had numerical advantage but were low on health, so they perished once they were stuck inside the twister.
The time it took Adrian to rid of the locusts also made enough time for the Anubis to recover. The Anubis waited for the exact time for it to attack Adrian as it could not just charge in blindly towards the twister that is Adrian.
What the Anubis did not expect is the twister started moving from its location. Adrian took exactly three seconds of spinning to even try moving towards someone. At first, he stabilized his bearing because spinning continuously for just one second would definitely make anyone dizzy.
