I have 5 families and in each im still waiting for:

Family 1: Blue butterfly
Family 2: Dragonfly
Family 3: Purple Bug
Family 4: Snail, dragonfly, Purple Bug and Moth.
Family 5: Dragonfly and Purple Bug

Families 2, 3 and 4 will have 100 trophies once the bugs are found! Family 1 also still needs perfect match and family 5 also needs a lottery win to get the 100 trophies!

For some reason in the last 2 days ive found quite a few new rare bugs in each family so my hope in completing the collection has risen dramatically!
