The completed picture began with “Sympetrum fonscolombii,” an item in the Smithsonian Institution collection. The holding unit is recorded as NMNHENTO. Free Nonogram does not republish the full source image. Instead, the reviewed source was reduced to a 10 by 10 grayscale field, tested at several pinned thresholds, and converted into the binary silhouette you just solved. The row and column clues were generated from that derived grid, then checked for one solution and completion by the site’s line-logic solver. This puzzle belongs to the Insecta Nature Atlas pack inside Nature Atlas. Its source ID, retrieval date, image hash, grid hash, rights evidence, and conversion settings remain attached to the puzzle so the derivation can be audited or withdrawn without guessing which asset was used. Compare the solved pixel shape with the object title rather than treating every square as a literal copy. Simplification is part of the puzzle-making process: fine texture disappears, while outline, balance, and a few distinctive masses become the evidence that makes the subject readable at small scale.
Numbers describe consecutive filled runs. Separate multiple runs by at least one empty cell.
Left click or tap to fill. Use Mark X for empty cells; a 0 means the whole line stays empty.
If you are stuck, use Hint for a bounded next step instead of revealing the whole answer.
