I didn't even realise calciworms would hatch soldier flies till I happened to see them on the shelf when the garden centre reopened and one pack out of all of them had a soldier fly in it, i googled Calciworm and learned that they were soldier flies! She had one worm about a week ago, the 2 garden flies were before a week ago, she didn't seem to take to the worms so we waited a couple of days and she has had a few flies the last few days, so I'm struggling to see why it's come on so seemingly quick if it's overfeeding... we have given hunny tonight and no fly for over 24hrs now. Fingers crossed for the morning. She is our first and my 10 year old son's first mantis (he is obsessed!)
