Hi Dennis, Possibly this critter is the culprit, link right from our own PBS site. http://pacificbulbsociety.org/pbswiki/index.php/… Ernie DeMarie in NY where the bulbs that are blooming are inside, namely a spiloxene, several oxalis spp, lachenalia viridiflora, Hesperantha hantamensis, a couple of Massonias, Lapeirousia plicata, and Walleria gracilis. - HOLY CRAP!!! I cut into my bulb and found live caterpillars inside. GROSS! What are they?? I never heard of anything in Ohio that would eat a Hippeastrum bulb from the inside out. YUCK. Dennis in Cincinnati
