@AskDrODR @bee_papers @MQBiology @SydneySOLES Thanks @AskDrODR ! We use the morning weight loss on our high precision scales as a measure of bee activity https://t.co/xrqaSoZIYJ It doesn't give us a number of foragers, but still a measure we can use to compare treatment groups.
@BinhNguyen_Mq@laowa_lens @Nikon_Australia Not sure in that case Binh, maybe two colonies that were too close to each other. They tend to defend a small territory I think.
@Myrmecos I think I can see a head on top with bead-shaped antennal segments and a well separated thorax. Could it be the pupa of a Diapriidae wasp? some of them parasitize Solenopsis in Europe, but I am not sure about Pheidole. The antennal segments just look slightly too big and round?
