Image 2 is a drain fly, also called a moth fly (Psychodidae, I believe). Often breeds in the organic scum in sink drains, especially in restrooms. Other breeding sites are floor/shower drains, elevator pits, and sump pumps. Key to control is cleaning the sites to remove the scum.

These rooms do tend to get a little more humid the central open areas of our building. We are in Wisconsin and typically warm and humid this time of year. My images are on the large side, so I will send in 2 emails. The first image is of an insect that looks like a tiny black speck to the naked eye, and we have been seeing them for months, our contracted pest control company ID’d them as fungus gnats, but when we viewed them under the microscope, they do not match up with fungus gnat photos. They were only found in the traps on the first floor of the building. Image 2 is a small flying insect, about 5 Mil. Long I’m hoping to find out if we have anything of concern to the collection, as well if any of them are indicators of other things that may be happening with the environment in our new building.

Do not click links, open attachments or take action unless you know the contents are safe] Hello everyone. My dad, confirms. The spider is indeed a female Leucage venusta, seen from underneath. The first description was made in Georgia (USA), from a male, in 1841, under the name Eipera venusta by french arachnologist Walckenaer. The name is inspired by the goddess Venus, for its beauty. The species is characterised by its green legs. It is now classified in the Tetragnathidae family. To my father’s knowledge it is only found in the US and Canada so far, where it is also referred as “Orchard Spider”. My dad added the following picture, where you can see it in all its glory. He also questions why on earth one would ever consider it a “pest”!? Unless one wants to include it on a list of victims of pesticides... Good point. Have a great week.
