0008075: Baby/vermin explosion
During the second winter of my fort, I suddenly had 10 dwarves (out of 67) give birth in rapid succession. Immediately after my view stopped recentering on the births, I noticed that my entire 5x5 outdoor refuse pile had been filled with creepy crawler remains. For several minutes I had not a single idle dwarf as they carried a constant stream of creepy crawler remains from my agricultural area. I had to turn on outdoor vermin remains collection so that they would move them into my qsp. Up to this point, my dwarves had not hauled a single vermin corpse from inside my fort, and I definitely would have known, as I am using an outdoor qsp for refuse, and had not changed the standing order for outside vermin collection up to this point. Now, however, there are 72 and growing creepy crawler corpses in my refuse pile, and they are still spawning on my food stockpiles. Because of the timing, I can't help but suspect a connection between the sudden surge in births and the massive influx of creepy crawlers.
I've never seen this before, I don't know.
These saves use the Phoebus graphics pack. The only mods were to add a display case building, a healing rate to nails and cartilage, the process plants to bag seed fix, and removing the grazer tag from elk birds. I haven't updated to 40.09 yet, but I didn't see anything in the changelog that appears even remotely related to this.

I fortuitously backed up my save moments before this started.

Does it reproduce if you move your save to 0.40.09?

May be related to or a duplicate of 0007902. I think they focus on different aspects of the same bug. The baby thing isn't really unusual, though - it just means you got a large number of married couples as migrants the year before.

I've migrated to .40.09 and tested the save. It does reproduce. The dwarven baby count is 9, not 10 as I originally stated.

@Talvieno, though I have seen surges in births many times, I've never seen them clustered so closely together. These births all happened within 1.5-2 minutes of unpaused gameplay. Normally I would have chalked it up to RNG, but due the correlation with the creepy crawler explosion it seemed possibly relevant.

Of note, as I've continued to play the fort, the creepy crawlers stopped spawning on my food at such a high rate. It took almost two seasons, but their appearance rate seems normal now. There are still a lot of live ones on my refuse and in the caverns, where there are no cats to kill them, but I can't say for certain whether it's an unexpectedly large number.

I'm getting an insane amount of vermin on the surface with cave crawlers. Also getting 10k-20k Bees per hive. This is on 40.23. The Severity of this should be raised.
