Multiattack

The spawn of Arbeyach makes one Bite attack and one Stinger attack.

Bite

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) piercing damage plus 4 (1d8) poison damage.

Stinger

Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 6 (1d4 + 4) piercing damage plus 13 (3d8) poison damage. If the target is a creature, it must succeed on a DC 13 Constitution saving throw or be poisoned for 1 minute. A poisoned creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Children of Arbeyach (1/Day)

The spawn of Arbeyach magically calls 1d4 swarms of insects. The called creatures arrive in 1d4 rounds, acting as allies of the spawn and obeying its spoken commands. The insects remain for 1 hour, until the spawn dies, or until the spawn dismisses them as a bonus action.
