Mine died in December and were collected in mid-Fall. It's entirely possible they died due to improper husbandry, though I'm not sure what I did wrong if so...Invertebrate Dudehttps://www.blogger.com/profile/08805593561535078108noreply@blogger.comtag:blogger.com,1999:blog-3693930219127879451.post-80397457738140511652017-12-19T16:55:58.315-07:002017-12-19T16:55:58.315-07:00The silverfish colony in my yard appears to be the...The silverfish colony in my yard appears to be the same species as the one in my house, and neither of them seems to be Lepisma saccharina.

I caught two rather large silverfish here in ID in a scrubland under some rocks, kept them in an enclosure with some darkling beetles, dry coconut fiber with a moist corner, dog food as the food with carrots offered as well. They lived a couple months, but never bred. I could have just had two males or something, I don't know, their scales didn't seem to rub off much, if at all. Wish I had gotten pictures of them, I think they were a US native. <br /><br />I think bristletails must have more specific care needs though, because I kept them pretty much the same as I keep my desert Tenebrionids, (and even housed them with some a few times), and they never lasted more than a week. Dry coconut fiber with a moist corner, driftwood and cardboard hides, and dog food with carrots for the diet, that's how I kept my bristletails. <br /><br />Thanks for the link, I've had that book for years though, someone on the Roachforum sent me the pdf for free. :) Invertebrate Dudehttps://www.blogger.com/profile/08805593561535078108noreply@blogger.comtag:blogger.com,1999:blog-3693930219127879451.post-86447133607334502642017-12-15T11:34:07.971-07:002017-12-15T11:34:07.971-07:00Free tasty roach book, if you haven't read it ...Free tasty roach book, if you haven't read it already:<br /><br />https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=10&ved=0ahUKEwiW6pGn0ozYAhVF3GMKHRcKByAQFghtMAk&url=https%3A%2F%2Fwww.researchgate.net%2Ffile.PostFileLoader.html%3Fid%3D57eb2559b0366d11f16bb2f6%26assetKey%3DAS%253A411112697810944%25401475028313142&usg=AOvVaw0kGami7UciLaFRTkdl2R8Z<br /><br /><br />Roachforum has mentioned it before, but from the looks of it it wasn't free back then.

Would you mind telling me what your failed silverfish and bristletail setups were like (if different for each species, state which)? I have seen wild silverfishes in rocky terrain under logs; these were quite literally between a rock and a hard place, but still healthy and scaly.<br />AlexWhttps://www.blogger.com/profile/00615656984206834928noreply@blogger.comtag:blogger.com,1999:blog-3693930219127879451.post-34114387478469997422017-12-12T21:41:24.109-07:002017-12-12T21:41:24.109-07:00And now I am really curious as to how to house Bri...And now I am really curious as to how to house Bristletails successfully, as I failed with both Machilinus and one of the Petrobiinae spp...Invertebrate Dudehttps://www.blogger.com/profile/08805593561535078108noreply@blogger.comtag:blogger.com,1999:blog-3693930219127879451.post-73471667556040243712017-12-12T21:26:47.412-07:002017-12-12T21:26:47.412-07:00Dang, I don't know what to tell you then, you ...Dang, I don't know what to tell you then, you could provide fruit but it will just mold and may cause more problems than starvation would.

When Kyle and Alan etc. go on collecting trips, they usually lose their Ectobiid colonies, in fact Alan sent me my Cariblatta minima, Latiblattela rehni and Balta notulata for free just so I could send him replacements one day, since he was going on a trip to AZ at the time. He did end up losing his C.minima and L.rehni cultures during the trip, luckily I bred successfully and sent him starter groups a few months later. :) <br /><br />This year though, he apparently found a way to keep his Ectobiids happy during long trips, but for some reason he didn't want to disclose what method he used...

From cf. Tanystoma maculicolle to Jadera haematoloma, the potential is always there. Since Jadera has aposematic colors and many flightless adults, death by mismolt seems unlikely, and yet it is still uncommon.<br /><br /><br />I am scheduled for a two-week trip (no internet) soon. It's a safe bet that Cotinis will starve to death in two weeks, and searching old roachforum stuff didn't help. How do you keep your delicate insects (Cariblatta, etc.) fed when away for very long periods? Cotinis isn't a desert darkling, so fruit would mold rapidly. <br />AlexWhttps://www.blogger.com/profile/00615656984206834928noreply@blogger.com
