(The Catalan populations rely on postural thermoregulation, if I’m reading the study correctly.)
Study finds Spanish butterflies are better at regulating their body temperature than their British cousins
Butterflies in both countries switch from heat-seeking to heat-avoiding behavior once air temperatures reach approximately 22°C. [British populations depend] more on microclimates for thermoregulation than Catalan populations.

Global assessment of free-ranging cats shows they eat more types of creatures than previously thought
They summed up their findings by suggesting that cats worldwide are eating pretty much anything that they are able to catch and kill, ranging from rats and mice to snakes and frogs, spiders, and of course, birds—many, many birds.

Lapinverkkoperhonen ja tundrahopeatäplä nähtiin viime kesänä Pallas-Yllästunturilla ja Lemmenjoella kymmenien vuosien tauon jälkeen
Metsähallituksen Luontopalveluiden kartoituksessa Lapin luonnosuojelualueilta löytyi kaikkiaan 35 uhanalaisiksi ja silmälläpidettäväksi arvioitua lajia. Pelkosenniemeltä […] löytyi ahmaspistiäisiin kuuluva laji Cubocephalus casparyani, jota on aiemmin löydetty vain yksi naarasyksilö Mongoliasta.

‘Like butter for bears’: the grizzlies who dine on 40,000 moths a day
Full of fat – some biologists call them “bear butter” – they’ve proved to be an important source of food for the region’s grizzlies. Biologists estimate about 200 bears each year feast on moths in the eastern portion of the carnivores’ range. Each gram of moth offers bears about eight calories, which means some bears will eat up to 40,000 a day.

Meadow spittlebug’s record-breaking diet also makes it a top disease carrier for plants
New research fueled in part by citizen scientists reveals that the meadow spittlebug—known for the foamy, spit-like urine released by its nymphs—can feed on at least 1,300 species of host plants, more than twice the number of any other insect.
