## What does the Bug 🐛 emoji mean?
The Bug emoji 🐛 shows a green caterpillar. Used far more often for software "bugs" (issues, tickets, debugging threads) than for actual insects — pairs with 🔧 for fix announcements. Also appears in garden / pest-control content, nature education, and metamorphosis / transformation metaphors (caterpillar → butterfly).
### Common uses
- Software bug reports, tickets, and fixes
- Debugging and QA threads
- Caterpillar → butterfly transformation captions
- Garden / pest-control content
- Kids' nature and life-cycle education
