The return of Mr. Safety!

Bryan Kotwica is a talented illustrator and climbing arborist with a knack for bringing safety to life through his art. From February 1992 until 2020, his “Mr. Safety” cartoons were a staple feature in the TreeWorker Newsletter. TCI Magazine is thrilled to renew its collaboration with Bryan and to bring his insightful and amusing cartoons to readers every other month.

Between November of 2020 and June of 2021, Tree Care Industry Magazine published “CSI for Bugs,” a five-part series of articles focused on honing diagnostic skills of arborists. This series detailed a forensic approach to diagnostics called symptomatology that uses clues left behind by a pest to help identify the culprit.

Part 1, Basics for Diagnosing Problems Caused by Insects and Mites

Part 1, “Basics for Diagnosing Problems Caused by Insects and Mites” (November 2020), focuses on how signs and symptoms can help arborists pin down the identity of the perpetrating pest.

Part 2, Diagnosing Injury Caused by Insects with Chewing Mouthparts

Part 2, “Diagnosing Injury Caused by Insects with Chewing Mouthparts” (February 2021), discusses symptoms caused by defoliating insects.

Part 3, Diagnosing Dieback Caused by Insects

Part 3, “Diagnosing Dieback Caused by Insects” (March 2021), discusses insects associated with dieback in the canopies of woody plants.

Part 4, Diagnosing Discoloration and Distortion Caused by Insects and Mites

Part 4, “Diagnosing Discoloration and Distortion Caused by Insects and Mites” (April 2021), looks at what changes in the normal color of leaves can reveal about the damage being done and the perpetrators causing it.

Part 5, Insect Products Provide Clues

Part 5, “Insect Products Provide Clues,” discusses products insects and mites leave behind that serve as clues to their identity much the same way a hair, clothing fiber or bodily secretions can be used by crime-scene investigators to identify the human perpetrator of a crime.
