   It seems that the recent rain brought out the slugs. Rebecca Reader-Lee writes: I went to Botanical Beach with my family on Friday, July 5th and, while we were there, I found a small (no more than 5cm long) slug crawling down a tree next to the path.  Jeremy Gatten writes that he believes it is a Scarletback Taildropper Prophysaon vanattae.

   Jeremy Tatum writes that there were three Painted Ladies, a Western Tiger Swallowtail, and a Red Admiral on the MountTolmie reservoir this evening.  I believe that this, and the caterpillar above, are the first Red Admirals reported to Invert Alert this year.
