How do you find all of the collection for bugs?

You have to buy the ticket in the flea market to dig in the dirt patches that show up in your yard. It is a fossil certification ticket and it shows up randomly. It was in my sons game in the first generation, my daughter still hasn't seen it and she's on her 15th generation. As far as the bugs go, they are random and rare. There isn't a way to find more of the collections, at least I haven't found any. NOTE: changing the date and time to cheat the game and make more money or any other reason seems to slow down random events in the game. I say this because my daughter and I have done this a lot in her game and she hardly has any collectables show up, and marriage proposals are few and far between. This is in every generation and she gets no random events that happen at all. She has not installed anti spam software either. My son has messed with the time or date and he has no issues at all and it seems to me that he gets more rare items and random events happening more. Which you will see by the 7th generation (or before) are things you look forward to. People may disagree but this is our own personal experience from playing the game. Good Luck

You usually find them at 6pm and are only given 3 to find
