Australia has endemic stingless bees... and now we have some in our yard.  Tetragonula carbonaria are not the European Honey Bees that most people know... they are much smaller and don't have stingers. In the Sydney region, T. carbonaria is at the southern end of its range as they only forage for food at temperatures above 18 °C. Keen observers of this blog will know that for a reasonable period of the year we experience outdoor temperatures below 18 °C. They also do not like temperatures above 38 °C. Outdoor temperature from August 2018 through the end of 2022. You can see that we had a few days in January 2020 that would have been too hot for the bees.  Outdoor temperature from August 2018 through December 2022. The green zone (18 - 38 °C) are temperatures at which the bees will forage. They will have very high mortality at temperatures below 0 °C or above 42 °C. Bees returning to the hive after visiting flowers... The entry to the hive box is through a 1/2 i

December was relatively mild and comfortable (median temperature °C). We decided to run an experiment in the last half of the month using A/C and no nighttime ventilation. Outside temperatures ranged from 10 to 35 °C, while inside we were a comfortable 20 to 26 °C. Temperature from inside and outside the house as the percentage of hours in 0.5 °C bins. I've scaled the temperature in hope that I will be able to use the temperature range for all months. Methods: I have taken the 5 minutely data from the wirelessTag sensors and calculated the median temperature for each hour and determined the proportion of hours falling inside of the 20 - 25 °C target temperature (using the R functions 'aggregate' and 'hist'). Inside includes data from the wirelessTag sensors spread across nearly every room of the house. Outside is the data from the wirelessTag sensors outside near the cubby house and HRV intake. The water wall and door data are not included. Energy product
