Because tokens aren't cards, they never count for undergrowth abilities.

Creature cards with other types, such as artifact creature cards, count for undergrowth abilities.

You can activate Izoni's last ability while its undergrowth ability is on the stack. This will increase the number of Insect tokens you'll create.
