I've been playing the same game for about 12 hours since release, and me and my son have reached a point where we're ready to tackle ladybugs. However, after looking for several in-game days, all around the map, we have yet to find anymore ladybugs. When we first started, they were all over the place. Now, there don't seem to be spawning. The only thing I can figure is that there is a limit to how many bugs can spawn in any given world and the Larva seem to be over spawning especially underground. I probably killed 20 of them underground (standing on a quartzite) and I got tired of killing them before I just left with more larva bits than I know what to do with. The other reason I've concluded this is because near my camp, on certain times during the day, a train of about 15 - 20 larva move in and out of hole in the ground. Also, this is impacting gnat spawn rates.. There are no more flying around the water sources, but that isn't halting my progression.
