Breeding Report: Cyriopagopus sp.”hatihati”

Adult Female Cyriopagopus sp.”hatihati”

Since the movement of the genus Haplopelma to Cyriopagopus I have been reluctant to write this report, but then I thought “I haven’t been so bothered that I’ve changed the labels on the tubs and they are unclassified as it is -who cares!”

With their closest relatives moving into Omothymus then I probably should start changing labels, for the purposes of this report I’ll just take it for granted that you’re following me  and know the spider I’m on about.

Our adult female Cyriopagopus sp.”hatihati” came from Lee @ TheSpiderShop on the 11th of August 2016 along with an immature male. As soon as they arrived I went about preparing her for breeding, she was fed extensively – as much as she would take and promptly moulted after a very short fasting period.

On the 15 of September the male was found, having completed his ultimate moult, mature and tiny (I had expected him to be small but not this small)

With some concerns for the males size and really not expecting him to be able to take on the female, I left him a couple of weeks to harden, eat and create his sperm web.

Post-ultimate male

Around the 1st of October 2016 I added the male together with the now fat fed female in a breeding box (80ltr plastic storage box) so that he has the chance to escape if possible and over the next couple of nights heard tapping and some spider shenanigans  – he didn’t escape! On the 3rd morning I checked and found a couple of legs stuck to a large bolus of mushed male.

The following weeks were all standard feeding, watering and housekeeping while making sure to disturb her as little as possible. This species is a little photophobic it seems and can completely freak out if you shine a torch into the enclosure let alone plod about inside the tub with a 30cm long tweezers.

December 6th 2016

It’s now well known that I cover my mated females tubs in T shirts and that I have lucky shirts that I wont change out (in “real life” I’m in no way superstitious but it’s become a ritual)

A very small white ball was found inside her burrow on the morning of December 6th. 66 nights since the male bit the big one.

I planned to remove the egg sac at around 28-30 days as I do for most Asian arboreal species but while sitting in the spider room I observed the female take the sac to the top of the cork bark and throw it away, exactly like she was excavating substrate from her burrow. It was day 18, I really wanted to leave it longer so sat and watched her for ages thinking she may pick it back up later.. nothing.

Absolutely gutted, I took the sac,easiest removal ever. Expecting either a rotten mess or a bunch of infertile eggs, I found neither – All were EWL and only a single bad egg!


Cyriopagopus sp.”hatihati” N1

Manually incubated and separated at spiderling stage resulted in 90 healthy miniature versions of what I believe is  a greatly underrated species.

It’s 2 months on and the female is massive again, possible double clutch coming??


 *Edit for Update*

March 15th 2017 – Female has constructed a second eggsac (double clutch) it looks to be nearly twice as big as the first
