About the Debug Bug Blocked black outline icon
A six-legged beetle with a domed shell and two antennae sits inside a circle crossed by a diagonal bar, the universal no-entry mark. Together they read as bugs eliminated rather than bugs found, so the icon works for debugging tools, QA and test-run results, antivirus and malware protection screens, bug tracker status badges, and CI pipeline dashboards marking a clean build.
The bug is centered with legs splayed symmetrically, and the slash runs corner to corner across the ring at a steady stroke weight. Small tick marks on the ring suggest a dial. Pair it with bug report, shield and checkmark icons, and keep it at 24px or above so the legs do not merge with the slash.
This is the black outline version of the debug bug blocked icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
