Perhaps a single Bladed Beetle would have no strength to fight back against a large Commander-grade monster like this, since even if it was the Level-35 Elite Bladed Beetle, it would not be able to withstand one swipe of the tail or one hit from the Earth Spike of the Level-38 Desert Rock Lizard Commander.
Similarly, no matter how strong a hunting dog was, it would not really be able to have any effect in front of a tiger.
But! There were 10 Bladed Beetles. Moreover, each of them possessed high movement speed and jumping methods, as well as uncommon attacks. The high movement speed, paired with the long leaps of the Bladed Beetles due to their beetle wings, made it very difficult for the Desert Rock Lizard Commander's fatal Earth Spike to hit them as they kept dodging them.
