For those of you who like bug collections, here are the bugs available in plant tycoon. When you catch the same type of bug twice, you automatically sell it. Common bugs sell for $5, uncommon for $20, and rare for $40. Some bugs can only be found with certain plants/flowers on your screen; in the chart I included the requirements, but the ones labeled with an asterisk (*) are ones I was not sure of (requirements courtesy LadyCFII -- I did not find this information myself). If you wish to know what bug is in a certain spot on the bug screen, I have labeled each jar with a "position number" -- for your convenience, the chart below is organized by position. Below the chart is a description of what happens when you find all 48 bugs.
