Selected Topics finished some projects on Friday ... our book, The Man Who Planted Trees and some genetics review. We have a lab on chromatography tomorrow.
In computer programming, we started checking our first qBASIC problems which will continue on Monday. We will start using For/Next statements and READ/DATA statements this week.
Busy weekend on the farm ... took a walk before church early this morning at sunrise. Lots of spider webs covered with dew. Hundreds of bowl and doily spider webs in the grass ... a small spider, Frotinella sp. , 2-4 mm ... didn't have my camera but I am not sure I could have taken one with my point and shoot. Their webs are like a bowl or small cup (about the size of a cupped hand) with a layer of web underneath. The spiders have a black and white abdomen and are very small ...

Frontinella pyramitela
GENUS and SPECIES: Frontinella pyramitela
These spiders are commonly called “bowl and doily spiders” and build neatly crafted webs. The webs consist of a bowl-shaped cup and underneath this is a flat, typically horizontal sheet. Sometimes above the bowl it weaves a maze of tangled web. Insects fall into this bowl and it captures its prey by pulling it through the flat sheet below. You can find this spider usually in coniferous woods on lower branches or in bushes and tall grass. This species is active in spring through mid summer. Some interesting facts about this species is that adult males and females will usually share the same web as a pair. Frontinella spiderlings are also known for their ballooning capabilities – going great distances and elevations.
