Visually Identifiable Spiders



Note: The purpose of this list is to indicate which species can be confidently identified without collecting a voucher specimen.  There will be two “levels” indicated here; 1) spiders for which the species can be identified, and 2) spiders  which can be identified at the generic level.   For spiders identifiable only to the generic level, the generic name will be followed by the number of species currently known for Ohio in parentheses.  Likewise, each family name is followed by the number of species known for the state, this will provide the reader with some indication of the size of the group of species not easily identified visually. This list is somewhat conservative, experienced spider students may be able to identify many more species than are listed here.  The use of a hand lens or portable microscope will enable observers to identify many more spiders as well as increase the certainty of the record.  All visual records should be accompanied by the information specified in the “submitting  a report” at the end of this document.

Submitting visual record reports


At a minimum the following data are required when submitting a visual record to the Ohio Spider Survey.


1. Locality where the specimen was observed.  The more specific, the better. Specify the nearest intersection or distance and direction from rural intersections.  Specify the latitude and longitude if possible.  These can be expressed to the nearest minute or using two decimal places when providing decimal degrees (with a GPS device).


2. Date that the specimen was observed (if possible specify the time).


3. Specify the substrate; for example ground, rock, plant (what type), building etc.  Was the spider in a web?


4. Describe the behavior; for example “hanging in web” “running on ground”. Indicate if there was an egg case or juveniles associated with the spider.


5. Specify age and sex if it can be determined.
