Loveliness of ladybugs part of winter’s huddled hibernators
Ladybugs do not migrate or move to warmer locations when the cool fall air approaches. Being an ectotherm, or cold-blooded organism which draws warmth from their environment, means that the winter cold will render these species inactive. So nearly all 450 native North American species hibernate.
When searching for hibernation locations, ladybugs will search for prime locations that are free from predators, are shielded from the wind, and unlikely to be disturbed. In their native habitat, hibernation locations could be under tree bark or in nooks of trees. But in the human developed landscape, there are other options. Cracks in buildings such as sheds and garages or in leaf litter under a deck can also fit the bill.
These prime locations are in high demand, so ladybugs are bound to bump into each other here. But they go beyond this, knowing that many ladybugs will provide better protection against the elements. To attract more towards these prime locations, they will emit an attractant pheromone similar to that used to deter predators and attract mates.
This results in ladybugs hibernating in the hundreds and even thousands. A group of ladybugs is called a loveliness, so a hibernating group can be referred to as a Loveliness of Ladybugs. More at https://www.ealt.ca/blog/huddled-hibernators

Solar project awaits judicial review decision
A judicial review brought forward by the Edmonton River Valley Conservation Coalition was heard Nov 19 in Alberta’s Court of Queen’s Bench, calling for the project’s approval to be deemed invalid and returned to city council for additional consultation. A decision by Justice Fraser is expected to be released in a written decision after reviewing the arguments made by both parties.
ERVCC legal counsel Alexander Yiu focused on how city council made the decision, arguing they were required to outright vote on if the river valley was an essential location for the solar farm as per a city bylaw. A vote on that specific question did not take place, but the bylaw amendments to allow for rezoning were approved.
On behalf of EPCOR, Michael Marion countered that they do not believe a specific vote on deeming the location essential was required. Even still, he argued that would not change the outcome of the seven councillors who voted in favour.
“Council had made a legislative decision to amend the area redevelopment plan to specifically contemplate this solar project,” he said. “We submit there’s no requirement to deem it essential.”
Marion also argued that the coalition does not have legal standing in bringing the judicial review forward in the first place because the solar farm is being constructed on property already occupied by EPCOR and would not be considered a public utility.
Despite the review, construction began on the project this summer with completion scheduled by next summer, as some solar panels have already been shipped with installation set to begin next month.

Melanie writes “Thanks for the newsletters! I’m so gutted to see the solar panels going up. Will you share an update on what the heck happened with the court injunction or whatever legalese was trying to hold this up?
