Why do Jumping Spiders make their hammocks at the very top?

[remarah1337]

I know jumping spiders make their hammocks on top, and I have made their enclosures accordingly. But why are they attracted to the highest point they can find? I couldn’t find anything online that explains why.

I had a jumping spider in my room once and it went to the very top corner of my ceiling.

My guess it’s probably an instinct to avoid predators?

its possible or maybe those are the spots its more likely to find its prey

Technically this isn’t always true. Not all jumping spiders make their nests at the very top. There are many different types of jumping spiders. There are tree-dwellers, bush-dwellers, grass-dwellers, ground dwellers, etc. and even species with extremely specific habitats such as Pelegrina tillandsiae, which lives exclusively in Spanish moss. Different types may make their nests in different areas. And even more specifically, different species. Many ground dwelling ones may make their nests under the substrate. Like Naphrys and Habronattus. Although they also make their nests in crevasses.

My sister’s Eris militaris adult male makes nests all over the enclosure. And my Platycryptus undatus adult female has never made a nest at the top. The only species I’ve kept that made a nest only at the top was a juvenile Phidippus putnami. (But I only kept it for a month)

My Phidippus audax has made her hammock at the very top of her enclosure.

I have one that made a hammock on the enclosure floor.

I've seen some web on plants close to the ground in shallower containers. Looks pretty sick!
