Mt 26ex twin flash

Habitus photographs were taken using a Canon 5D mark IV digital camera with a Canon EF 100 mm USM macrolens. A Canon MT-26EX twin flash was used as the light source. Fig. 1A was taken using a Canon 5D mark IV digital camera with a Canon EF 70-200 mm f/2.8L IS III USM lens. Photographs of smaller characters were photographed using a Keyence VHX-5000 digital microscope with a Keyence VH-Z20R zoom lens (20-200×). The photograph in Fig. 4 was taken using a Canon EOS 50D by Lu Qiu, while that in Fig. 7 was taken using an iPhone 14 smartphone by Yi-Wei Wang. The images were processed and combined into figures using Adobe Photoshop CC 2019. All photographs were taken by the authors, except those with captions.

The amber specimen studied herein was found in the Hukawng Valley, Kachin State, northern Myanmar (26°21′33.41″ N, 96°43′11.88″ E) [13 (link)]. The age of Kachin amber has been dated to 98.79 ± 0.62 Ma based on U-Pb zircons (earliest Cenomanian) [14 (link)]. We are mindful of the ethical concerns pertaining to Kachin amber and we declare that the specimen reported herein was collected prior to 2015, and it is, therefore, free of current ethical concerns surrounding the post-June 2017 acquisition of amber from the region [15 (link),16 (link),17 (link)]. The amber piece is conserved in the research collections of the Qingdao University of Science and Technology, Qingdao, China (QUST).
For a better view, a handheld engraving tool was used to cut the amber piece and sandpapers of varying grain sizes and rare earth polishing powder were used to polish the piece. Observations were made using a high-resolution stereomicroscope (D-07747 Jena, Leica, Germany), while photographs were taken using a Canon 5D SR camera with an MP-E 65mm f/2.8 1–5× macro lens, while a Canon MT-26EX twin flash was used as the light source. Zerene Stacker v. 1.04 was used to produce extended depth images. All of the final images were cleaned and arranged in Adobe Photoshop CS5 Extended (Adobe Systems, San Jose, CA, USA).
