Group Edmund Burke School

The dobsonfly was caught during the day between 80-90 degree Fahrenheit weather.

Putative identification Arthropoda Hexapoda Insecta Megaloptera Corydalidae


Extraction kit DNeasy (Qiagen)

Gel electrophoresis system MiniOne
Buffer TBE
DNA stain GelGreen

Protocol notes

DNA extraction: The dobsonfly’s abdomen was extracted to use for the DNA sample.

Gel electrophoresis lanes:

Lane 1: 10kb DNA Ladder
Lane 2: Arthropod Sample A-1
Lane 3: Arthropod Sample A-2 (the dobsonfly)
Lane 4: Arthropod Sample A-3
Lane 5: Arthropod Sample A-4
Lane 6: Positive Arthropod Control
Lane 7: Negative Arthropod Control
Lane 8: Positive DNA Control
Lane 9: Water


Sample A-2 tested negative for arthropod DNA, which means an error occurred with that DNA sample somewhere in this process or one of the earlier processes. We know we can trust our results have no contamination because our controls tested correctly.


Wolbachia presence Unknown
Confidence level High
Explanation of confidence level

Since the dobsonfly sample tested negative for arthropod DNA, it is unknown whether or not the dobsonfly is infected with Wolbachia.
