| Injuries were visible as sclerotized scars in the female ovipositor, and their occurrence increased with mating frequency. |
| The cuticle of juvenile stages is thin and weakly sclerotized, and sternal and tergal plates are barely recognizable in the light microscope. |
| The majority of the fossil record consists of biomineralized or sclerotized remains as they have a high preservation potential. |
