Can anyone tell me when katydid eggs typically hatch? They are from captive specimens of two different species. I have Greater Anglewing eggs from two different females, which were laid two months apart. The second female just laid hers yesterday (Nov. 21). I also have Black-legged Meadow Katydid eggs laid by two different females, about a month apart. I was able to film both the Black-legged Meadow Katydids females laying their eggs. Unfortunately, I missed the greater anglewing yesterday by just minutes. She was cleaning off her ovipositor when I found her, and the eggs weren't there when I left the house a few hours before.I need some idea of what month to expect them to hatch next year so that I can collect appropriate food in advance. Suggestions as to what is "appropriate" food would also be welcomed. I will release most of the babies, but want to rear a few of each species and document their growth. Can anyone provide any help? I live in northern Illinois if that makes a difference as to when they will hatch. For now, the eggs are on branches in very tall ventilated jars on my screened porch so that they will go through a normal winter. But I have no idea, not even a vague one, as to what month katydids are typically born. I never find them until they are adults or just prior to their last molt. I'm actually surprised that my Greater Anglewing female and Prairie Meadow Katydid male are still hanging on in late November. I've never had any katydid species live into late November before. There's no natural food to bring inside for them now. The anglewing is living on a sedum plant that I potted for her, but it is almost gone. She's also got romaine lettuce and gel cricket food. The prairie meadow katydid has only romaine lettuce and gel cricket food. Both seem to be doing okay so far. Any suggestions as to what else to feed them? I want them to have as long and healthy life as possible, although I realize both are at the end of their lives.
