Monarch butterfly, Danaus plexippus, the species appeared in Australia around 1871, when its food plants were introduced, Bunbury, Western Australia (Photo by: Auscape/Universal Images Group via Getty Images) Volunteers counted nearly 250,000 western monarch butterflies during the annual Thanksgiving tally – a 100-fold increase from the year prior -- offering a glimmer of hope for the declining butterfly population.

However, conservation biologists with the Xerces Society for Invertebrate Conservation say it's too early to celebrate the jump, the highest count since 2016.

Last year's count resulted in just 2,000 of the black and orange butterflies, the lowest ever since the annual count began in 1997."We know that these monarch numbers can go up and down even in large swings, and we've seen that in the past," Western Monarch Lead Emma Pelton said. "Historically, we've never seen an increase of this large in a single year in terms of the increase from 2,000 to over 200,000.

But we've also never seen the population as small as it was last year. So insect numbers can do funky things, and we'll learn more as more years of data can have come in."One theory is that the weather offered a respite for the delicate insects.

Omicron 75% less likely to cause death than Delta COVID-19 variant: South Korean data
Omicron coronavirus variant are nearly 75% less likely to develop serious illness or die than those who contract the Delta variant, real world data released on Monday by South Korea’s health authorities showed.A study by the Korea Disease Control and Prevention Agency (KDCA) of some 67,200 infections confirmed since December showed the Omicron variant’s severity and death rates averaged 0.38% and 0.18%, respectively, compared with 1.4% and 0.7% for the Delta cases.The KDCA classed severe cases as people who were hospitalised in intensive care units. COVID cases exceed 400 million globally as Omicrons spreads Around 56% of 1,073 people who died over the past five weeks were either unvaccinated or had received only one dose, the study showed, with people aged 60 or older accounting for 94% of deaths.More than 86% of South Korea’s 52 million population have been double vaccinated and nearly 60% have received a booster shot.South Korea had kept cases and deaths relatively low thanks to widespread social distancing measures and aggressive testing and tracing.The Omicron variant has led to a surge in cases — daily new infections topped a record 100,000 last week — but authorities have pushed ahead with slightly easing social distancing rules amid the lower fatality rate and ahead of a presidential election next month.Contact tracing and mandatory isolation for vaccinated people was scrapped in favour of self diagnosis and at-home treatment to free up medical resources.

Next Covid variant could be worse than infectious Omicron, Chris Whitty warns
Boris johnson today (February 21) said that the response to the pandemic would be "vaccine led" as he announced that all lockdown restrictions will be ending by Thursday. Speaking after he announced all remaining Covid restrictions will be axed, the PM said there "may be significant resurgences" and "it's very possible that those will be worse than Omicron".Whitty said at a Downing Street press conference that new strains were to be expected and while some "will just disappear" others could escape vaccines and result in a fresh wave in hospitalisations.Prof Whitty said: “Some of those new variants will just disappear, but some of them will cause us significant problems and they could be either more vaccine escaping but as severe as Omicron, but the net effect would be actually more people end up in hospital because a lot of our protection is from vaccination, or it could be more intrinsically severe, because Omicron came from a much earlier variant.”He added we “could certainly end up with something which is more likely to lead to hospitalisations than Omicron”, adding that winters are expected to be “tricky” even in the absence of significant new variants due to the combination of Covid, flu and other respiratory problems.The Chief Medical Officer also urged Brits who test positive for Covid to self-isolate, even though they will no longer be forced to do so under law.“As we look at the next weeks, we still have high rates of Omicron and I would urge people in terms of public health advice, and this is very much the Government’s position, that people should still if they have Covid try to prevent other people getting it and that means self-isolating," he said.
