All Myrmex are unable to use agency as their instincts override free will. So they must roll an intelligence check to freely choose an option out of four in a limited amount of possibilities, if fail intelligence check player must roll 1d4 to choose a option in a appropriate possibility. All options and possibilities are; 

An Unknown Creature Appears(creature that is not within colony)

You're Attacked

You Find Food

You Discover Valuable Resources

You're Given an Order

You're Alone

You Encounter an Injured Ally

You Encounter an Enemy Stronger Than You

No Immediate Task Exists

A Loud Noise Occurs

The Colony Is Threatened

If a unlisted possibility occurs the player may act in their own will as long as it benefits them/the colony(the DM adjudicates if not clear)

You gain the ability to climb/cling to any surface as long as one of your six legs is on it. Also climbing no longer cost an extra movement. In addition, when you make a running jump, the distance you can cover increases by a number of feet equal to your dexterity modifier 

Use the biological tools on your body to gain  abilities, new abilities are:

Mandibles: user deals 1d10 slashing damage to creature in 5ft or user can instead burrow and create a tunnel at 75% of users movement speed.

Antennae: You wave your antennae across the battlefield. For one round: Invisible creatures within 30 feet cannot gain advantage from being unseen. Hidden creatures automatically reveal their location if they move. You gain advantage on Perception checks. User knows everything what is going on in 15ft as long as it is on the same plane

Stingers: user deals 1d8 piercing and inflicts target creature in 10ft with poison condition the more a target creature is stung the more poison conditions are stacked upon it. also their is a 10% chance the target also gains Paralyzed condition

Maul: user uses mandibles twice then stinger on a single action, 3 time used before user can recharge by completing a short rest

trophallactic fluid: user converts 1/4 of last food they ate into 'Ant Milk', user can feed other creatures to stave off hunger for 8 hours and heal by 1d6 amount, if used 4 times user must eat another food source to recharge this action 

Compound eyes: user boost overall accuracy by 30% and give adv on preception

Molting: user sheds past exoskeleton removing any active conditions and regenerating lost limbs by resetting to the default state but, after taking this action for 1 round any action against user is a crit

On skill first time use Broodmother Myrmex lose their wings and the ability to fly. User creates an egg or an egg-cluster(a group of 5 eggs in 1 item form, can only be used 3 times per long rest) that can develop into a type of Myrmex. Each egg has 5 hit points, and must go through stages of development before becoming the desired Myrmex, the development's appearance is similar to ants. The egg stages are;

• Egg: an immobile item, size: tiny, 2 hitpoints, sticky it clings on to surfaces
• Larvae: an immobile creature, size: tiny, 8 hitpoints, must be fed every 15 minutes or it begins to starve after 2 rounds of starvation the larvae dies
• Pupae: an immobile creature, size: tiny-small, 10 hitpoints, Armor class: is 14(natural armor)
• Adult: the desired Myrmex

The development time varies depending on the type of Myrmex caste that is developing. Each Myrmex caste can have different types of jobs once the job is chosen it cannot be changed after death, the Myrmex and their jobs are;
