Typical Orbweavers (Subfamily Araneinae)Observer
zpezzilloDescription
very interesting little spiders. they build their small webs on the dorsal side of leaves that have a slight concave shape (in this area usually Clermontia spp. but sometimes on ginger) and hang upside down in the web. Have only seen these in mesic forest of lower Waikamoi and upper Makawao Forest Reserve.

lamebrainDescription
Found while trimming small trees. I think this is Thymoites but I cant find a similar looking epignyum in the literature for this genus. I'm new at this so maybe there's something obvious I'm not seeing...

I will be uploading better photos to see if this idea is correct. It could've been a dead arrow orbweaver.

Hobo Spider (Eratigena agrestis)Observer
rangerharlesDescription
Really on the fence about this one. Multiple barn funnel weavers have been found in this unit. But some traits here point to Eratigena agrestis. The abdominal pattern looks suspicious, as well as the shape & size of the palp. The sternum is confusing, I can’t really make out for sure if there is spots or not, even under a loupe, but it doesn’t seem like it! Missing one palp, maybe it had tried to mate with one of the Tegenaria females😅
