Results
Wolbachia presence No
Confidence level High
Explanation of confidence level

If our arthropods had wolbachia, there would be a bright band aligning with the +DNA control (the brightest band). Because the arthropods DNA does not align, we know they do not have wolbachia.
Wolbachia 16S sequence
Arthropod COI sequence
Summary The Coccinella septempunctata was found to be negative for Wolbachia.
