#LoveSpecies nominee: horrid ground-weaver

Nominated by: BugLife

Horrid ground-weaver spider

Why do you love it?

The horrid ground-weaver (Nothophantes horridus) is an extremely rare endemic money spider so called because of a corruption of its Latin name horridus which means hairy. A look at the spider under magnification indeed shows that it has a series of hairs or bristles sticking out from all its legs. It is just 2.5mm across, hence the need to observe under magnification. Until last year the only images available of this enigmatic little spider were a line drawing and a photo of a specimen in formaldehyde.

The spider lives in limestone cracks and crevices and is a nocturnal hunter across scree slopes most likely feasting on springtails and other small invertebrates. The IUCN added the Horrid ground-weaver to its list of endangered species in 2016 and it is probably the UK’s most rare spiders listed under Section 41 of the 2006 Natural Environment and Rural Communities Act.

What are the threats to the horrid ground-weaver?

The spider only lives on three recorded sites in Plymouth one of which has been developed into an industrial estate and another of which in 2015 was subject to a planning appeal for development. Buglife mounted a campaign to save the site, Radford Quarry, and were delighted when the planning inspector agreed to prevent development.

Many people who supported the campaign to save the Horrid ground-weaver were not spider fans indeed some were arachnophobes but they saw the importance of saving it – one supporter Helen stated on the petition “Not a panda, but just as important.”

What are you doing to save it?

After saving the site Buglife raised funds to study the spider which has now been found on a further site and we have also managed to obtain the fist ever photos and video of the Horrid ground-weaver in situ. All this was possible because over 10,000 individuals signed the petition and donated by a crowd funder. 2017 sees another obscure endemic under threat Fonseca’s seed-fly found on the north east dune scape of Scotland its habitat threatened by a golf course. Currently the only specimens of Fonseca’s seed-fly are in formaldehyde there are no photos.

Dec 19

Hanukkah, one of the most widely celebrated holidays of the Jewish tradition, commemorates the miraculous supply of oil for the Holy Temple in Jerusalem.

In honor of the 8 days of Hanukkah, Arkive presents eight wonderful species, some native to Israel and others we think uniquely exemplify this special holiday!

What’s in a shape?

Common starfish

The Star of David is a recognizable Hebrew symbol with 6 distinct points. Most of nature’s “stars” have five points like the beautiful and resilient common starfish that can survive adversity even to the extent of re-growing its arms as long as its core stays intact.

A celebration of lights under the sea

Hanukkah is often referred to as the “Festival of Lights” and celebrates the illumination of the menorah. Deep below the surface of the ocean, species such as the firefly squid produce its own celebration of lights! Utilizing its bioluminescence abilities, the squid camouflages itself by mimicking the light coming from the ocean surface.

Spinning, spinning,  just keep spinning

Spinner dolphin leaping and spinning

The dreidel, a popular toy for children during Hanukkah, has symbols that denote the phrase “A great miracle happened there”. Much like the dreidel, the spinner dolphin emerges from the water spinning high in the air. It is hypothesized this behavior might be used to dislodge remoras or might simply be dolphins having fun.

Are the latkes ready yet?

A traditional food during Hanukkah or the Feast of Dedication is the delicious latkes composed mainly of potatoes. Japanese macaques are also big fans of potatoes. In a unique display, a female in one troop of Japanese macaques washed potatoes in seawater prior to eating them. Now all members of her troop display this distinctive behavior!

 Would the Hoopoe by another name sound as sweet?

The beautiful and colorful Eurasian hoopoe is named for its distinct vocalizations of hoop hoop hoop. Its splendid orange-tan plumage and regal crest differentiate it from other birds in the area. The hoopoe was officially chosen as the national bird of Israel in May 2008.

Someone needs a quick desert catnap

The cuddly sand cat strongly resembles a domestic cat, but don’t be fooled by its looks. This is one hardy kitty since it is the only cat that lives foremost in true deserts including the desert regions in southern Israel. With limited water resources, it obtains the majority of its water from its diet.

From 8 candles to 8 legs

Female crab spider

One of the most iconic symbols of Hanukkah, the Menorah holds 8 candles for each day of the holiday, and an extra candle to light other candles and/or to be used as an extra light. In nature the arachnids defining characteristic is the presence of eight legs like that of the vibrantly yellow crab spider. This species has the extraordinary ability to alter its color to match its background!

Are my tree rings showing?

Olive trees

It might still look like a sapling, but the olive tree is the world’s oldest cultivated plant! It transcends time and cultures through its worldwide recognition as a symbol of abundance and peace. In September 2007, Israel elected the olive tree as its national tree.

Happy Hanukkah!
