First ever joro spider! So beautiful against the sun with her massive web. An introduced orbweaver from east Asia that's caused some wack news articles. Stuff like "giant flying spider invades the east coast!1!1!1!!". They do balloon but their invasion is not so dramatic.

Some crane flies in the genus #Geranomyia produce a little gel nursery to develop on leaves in the tropics. There they graze on algae & other organic matter. The mass provides moisture (other spp. live in water/soil) & likely protects from predators. #Tipulidae #Limoniidae #FlySchool2026 Costa Rica

What time is it? It’s #Cheliceratime & #FossilFriday! Today's entry is our first oribatid mite! It's also to my knowledge this species' first paleoart! All the basic infos are here but if you want to learn more, there’s more in the thread below!⬇️🧵 #mite #arachnid #paleoart #bugsky #invert 1/3
This extinct mite is among the oldest named oribatids. It was discovered in carboniferous rocks from Northern Ireland, hence its name since Ireland is called Hibernia in Latin.

Size : 430 µm
Time period : Early Carboniferous
Paleoart speculativometer : Mostly based on another taxon

The animal drawn is a yellow mite with long setae on its back

Keeping the Pride Spirit Alive! 🌈 Hope you all celebrated this past month! We’ve gathered some fascinating examples of queer behaviour in nature to share with you.
Happy Pride Month!Queer behaviour is common in nature. On the Hawaiian island of Oahu, 31% of Laysan albatross pairs were found to be female-female[1. In clownfish groups, when the dominant female dies, the next-in-line male changes sex to become leader[2]. Bonobos engage in frequent same-sex sexual interactions, which may facilitate cooperation[3]. Such behaviouR Was historically understudied due to anti-LGBTQ+ discrimination.Diversity, inclusion & equity are vital for good science. At ABC we are proud to support and celebrate all LGBTQIA+ students & scientists!.

ヒメマメザトウムシ。体長は1.5mmほど。主に4〜6月に見つかりますが、マメザトウムシのように樹表面に出てくることはなく、ずっと落ち葉層やガレ場などで暮らしています。 神出鬼没で新規の場所で狙って探すことはかなり無理があるものの、いると分かっている場所であれば丹念に探すと大体毎年見つかります。目がすごく大きく見えますが、それはアイシャドウのような黒い部分のおかげ。それでも他のグループと比べたら頭胸部に対しての目の比率はかなりのもので、ちゃんと獲物を目で認識して捕食する肉食の種です。

Netcasting spiders modulate silk thread stiffness via a tailorable multi-fibre meta-structure to construct a web that is hyperelastic and high load-bearing at the same time. Read about our discovery in PNAS: doi.org/10.1073/pnas... 🔓 & with video content!
Figure showing a video still from a high speed video of a netcasting spider capturing a cricket with its elastic web held in the front legs. Left to the video still there are load-strain diagrams of different lines in the web showing that the upper lines are stiff and strong and the lower lines are highly extensible. Left to the diagrams there are scanning elactron microcopy images of the dfifferent lines, showing that the upper, stiffer lines are cables made of many parallal fibres, whereas the lower lines have a soft central core with adjoined looped fibres. The degree of looping correlates with how much the spiders post-process the silk after spinning. This way they can tailor the stiffness of each line in the web separately and create a vertical stiffness gradient throughout the whole web architecture from stiff and strong in the upper load bearing frame to soft and hyper-elastic in the lower part that is rapidly extended and thrown against the prey at high speed during the predatory strike.
