I'm not sure which is the right forum to report book bugs in, so I'm putting it in General. But it would be good if there were a sub-forum just for these. Or is there an email address at logos to send in such things?
The Tyndale Bible Dictionary doesn't have links under its entry INSECT from the individual insect names (where it says "See...Ant; Bee; Flea; Fly; Gnat; Grasshopper; Locust; Moth; Wasp") to their main entries.
