Some of the walls in the bug temple are diggable, but so many are not that it is not possible to make real progress.
The bug temple has been beefed up considerably since 1.0.0 with the simple addition of the see invisible intrinsic for the bugs. Low (or even high) level spellcasters are no longer going to be able to finish this area easily.
The rewards have been toned down: only three SoCRs, six PoUH, eight SoMM. The wand of fireballs has ten charges, the wand of teleportation has six charges.

The bug-infested temple consists of two parts: the bug wilderness (BUGWIL) and bug cave (BUGCAV). The wilderness part's outer limits are scattered with greater claw bugs, that low-level spellcasters can bolt to death (be very cautious!). Around the down staircase, there are eight killer bugs.
Note that both greater claw bugs and killer bugs have high speed, breed, have multiple attacks and bypass the PC's PV. This means that they are what they're called - killers - in melee.
Eating a greater claw bug corpse increases speed, gives +3 Dx and -6 Wi. Eating a killer bug corpse also increases speed, gives +6 Dx and -12 Wi. The increases are no longer guaranteed in ADOM 1.1.1; the upper limit seems to be around 30.

The 'g's are greater claw bugs and 'i's are killer bugs. ]'s represent
named marble statues. The numeral 1 represents secret doors. Teleportation
doesn't work in BUGCAV.All the marble statues can be picked up and broken, like normal ones. However, there's another meaning to them; reading. They're in place to honor the prerelease testing group of version 1.0.0. Here's a compilation of what they all mean and what you get from them. The format for the list is: real name of tester - statue text - reward for breaking the statue, besides rocks

Note that some of the rewards' stats may vary and that they are all cursed. However, those potions of ultra healing, scrolls of magic mapping and especially the scrolls of chaos resistance are a gift that makes visiting the Bug Cave very worthwhile.
There is one more statue, an "unfinished statue of an unquestionably famous hero" in honor of Raymond Martineau. No reward for breaking him down, though.
Breaking the center statue and the statue ten squares west + one north stops the breeding of the bugs and results in an appropriate line in the accomplishment list at the end of the game.
