Turns out ecologists and entomologists around the world have been warning about declining insect numbers for years. The culprits are climate change, habitat loss, light pollution, intensive farming, pesticide and fertiliser use. But it’s a struggle to get people to act.
It’s not just about bees and butterflies, the poster children of the pollinator world. Other, less photogenic pollinators such as hoverflies, moths, wasps, soldier beetles and earwigs are also showing declines. Several of these species don’t just pollinate. They also eat the pest insects that ruin crops.
Already, in the apple and pear orchards of south-west China, depleted populations of pollinators have forced farmers to hand-pollinate their trees, carrying pots of pollen and paintbrushes with which to individually pollinate every flower. If it sounds labour-intensive and time-consuming, that’s because it is.

The amazing value of the eLife Assessment, demonstrated:
"The fascinating role of neuropeptide Bursicon and its receptor in shaping insect seasonal polyphenism", by Zhang et al. 2024
https://elifesciences.org/reviewed-preprints/97298
"This *important* study shows that low temperature activates the bursicon signaling pathway during the transition from the summer to the winter form and that it affects cuticle pigment and chitin content, and cuticle thickness."
"The study's *solid* set of experiments and results reveal a role of bursicon signaling in regulating features of polyphenism related to the exoskeleton. Nevertheless, they only *incompletely* substantiate the authors' claims about the regulation of polyphenism itself."
In which other journal would a reader get such a valuable reviewer comment like this, right away? Only at @eLife ! ELife's Assessment for the win.
I'm back from a week along Colombia's Caribbean coast! It wasn't a photography trip per se but I did manage a few sessions, and I'll be posting buggy highlights over the next weeks.
Here's a teaser, a little stingless bee pollinating Mexican sunflower:

Surprise observation this afternoon: Homotropus sp. An ichneumonid wasp, about 5-6 mm long.

Ant biologists thought the small, strangely-shaped Manica parasitica from the Sierra Nevada was a social parasite of another ant species, but the truth is even stranger.

The Venezuelan poodle moth is a beautiful animal. There was an article back in 2012 in #TheAtlantic https://www.theatlantic.com/culture/archive/2012/08/venezuelan-poodle-moth-internets-favorite-real-life-pokemon-tk/324111/ that traced the story and found out that it was real and not an internet fake.

That album by Arthur Anker contains many more photos of extraordinary neotropical moths https://www.flickr.com/photos/artour_a/albums/72157603542118616/with/3947813697/ plus a few other insects.
The photos are simply out of this world. Here are a couple of my favourites:

The enigmatic Acanthoponera minor, an ant that is occasionally seen patrolling the low vegatation of wet neotropical forests, about which little is known. I photographed this one in Ecuador.

Quite specific, but a very interesting article about #ants and their early evolution. The authors propose a 3 step scenario based on fossils and their interpretation. Really fascinating !

Background Many factors can influence circadian rhythms in animals. For acoustically communicating species, both abiotic cues (such as light and temperature) and biotic cues (such as the activity of other animals), can influence the timing of signall…PeerJ
