Today's high of 57 degrees F presented a good opportunity to complete a brief assessment of all colonies. After a quick peek from both above (via screened inner cover) and below (via screened bottom board), the only colony that was provided additional supplemental sugar was #2011.
It was also time to conduct the Winter 48-hour mite drop assessments (as attached).
Finally, I evaluated the mite drops for damage. This was the first time I have done so following a conversation with Mr. Krispn Given with Purdue University relative to evaluation of mite mouth parts (gnathsoma). In short, I wanted to clarify with him whether the Purdue protocol included evaluations for damage to the gnathsoma (which he confirmed) relative to the 'New Damage Categories' paper published in 2017.
While I will spare you the gory details, I now feel more confident in evaluating the mouthparts for damage- in fact, it is now the first place I focus on for assessments. The following video gives a good sense of a live (and undamaged) mite anatomy from the ventral side:
