In every city and even in villages, you can find up to 120 beetles - they are found in random places on the map. What do beetles look like? They look like a mole with green glowing eyes and a white flower on its head. An example in the screenshot below:
How to hunt insects
First of all, your team must have at least 3 players. This is very important because some players may steal your bug if you don't have a team yet.
If you find it difficult to assemble a squad, you can create one and invite mercenary bots. Just go to Team - Create Team and be sure to check the Mercenaries section.
When everything is ready, wait until the Beetle Hunt event starts, then click on its icon and select the card you like.
You will be moved to the map, and now you can start looking for bugs.
Once you find one, click on it and challenge it.
Then you will go to the arena where you need to defeat the bugs and the boss and collect your reward.
