A passive security sweep found one of these about a month ago and fool heartedly breached the mud like outer casing. Quick reflex and action promptly destroyed 2 or more small arachnid type creatures that quickly rushed forward. This effective but heavy handed response unfortunately made post mortem identification impossible due to a lack of any discernable structure or tissue. A month passed and a similuar sweep came upon another attached to a single needle on an Alberta spruce in inventory. Proleminaries show an egg type housing unit and the materials appeared to be a mud saliva mixture. So far the original mud seal has continued to hold the horrors inside but I believe they are growing anxious if not suspicious. Help with identification will be looked at most graciously. If a need is suggested to breach the mud casing to obtain further photographics please state so and it will be given thorough consideration after security and containment procedures are drafted and put in place. Thank you once again.
