Update as of 07/25/2021
I've noticed bugs have been cycled this year. I saw no bees this summer, and I'm seeing more exotic bugs like Green Hairstreaks, Small Blues, Peacocks, and Mantises. I'm still seeing the more common bugs like Large Whites, Ringlets, Swallowtails, Clouded Yellows, Emperors, Agrias's, Grasshoppers, and both Destiny butterflies.
I've not seen any Tigers, Monarchs, Ladybugs, Black Ladybugs, worms, or Spiders.
As far as I'm concerned, regular Spiders are extinct in Graal. I've not seen a regular Spider in years, and others have said the same.
I've not been able to find worms, either.
I dislike this cycling between different bugs biannually as it's always been done. The values are still low and the cycling doesn't make much sense anymore, especially when half of the bugs are worse in value than others.
Ground bugs like Roaches, Beetles, Pillbugs, and Waterstriders seem to be around all year like normal. I haven't actively looked for Centipedes but I'm sure nothing's changed.
Still gonna wait for value changes.
