caltatapach (FCbk11f93v)
This compound glyph features an assassin bug (caltatapach), is included in this digital collection for the purpose of making comparisons with related hieroglyphs. The term selected for this example comes from the text near the image in the Digital Florentine Codex. There is no gloss, per se. This example shows a bird’s eye view of a bug with large, shell-like wings on its back, eight legs, two antennae, and ridges on its body. The tip of its rear end bumps up against the roof of a house (calli), which serves as a phonetic indicator that the bug’s name starts with cal-. This building is shown in a partial ¾ view, facing toward the viewer’s right. Shading gives it some three-dimensionality. This, and the landscape setting visible in the contextualizing image shows European artistic influences.

This bug’s name derives in part from tapachtli, seashell. It may be that the wings are hard like shells. This digital collection has no other examples of the caltatapach bug at this point in time (November 2025). While this is not a traditional compound hieroglyph, it is a late expression of that form of writing.
