August 17, 2017 . Leucauge venusta: music and mating

This morning, a real treat: Watching male and female Leucauge Venusta

Male (upper right) and female (lower left)

Male approaches and is rebuffed by the female

He uses his 3rd legs to pluck the radial strands of her web

The female

More plucking - hoping he will find the tune she wants

Here is a video of a failed approach and then success - after a lot of plucking the radial web strands.

August 9, 2017: White Ibis foiled by a turtle

I look for patterns of behavior in my nature walks.   Today, I saw a white Ibis with a piece of trash in its beak.  This seemed unusual to me so I watch and took photos for about 20 min.  Got home and discovered that the Ibis had caught a small turtle (Florida softshell turtle, Apalone ferox.  The ibis was unsuccessful penetrating the shell and after quite some time.  Gave up.  Here is the pictorial story.

Aug 02, 2017 Emerging Tetragnatha elongata spiderlings

Tetragnatha elongata spiderlings

I've not seen spiderlings in the wild so I picked 2 grape leaves, each with an egg cluster on it, and placed them in a ziplock bag along with a small wet paper towel segment.  After a week of waiting, they emerged last night while I was sleeping.  Here is the story.

An egg cluster patch.  The open area in the upper left of the patch is the escape hatch. Two spiderlings to the left and two in the middle right in the crease of the grape leaf

Released in the wild - an idea of the size scale

They manage to build silk bridges between the leaves in a matter of minutes

July 31, 2017: Tetragnatha egg cluster

This morning was Tropical Storm Emily poured inches of rain on us.  By afternoon it partially cleared so I visited my Tetragnatha cluster.  Today looking for eggs - which I found.
