It is a breakfast time so... bon appetit my Friends!!! :>

Ok, I must be honest, this picture was taken in the laboratory in my department - nothing like this creature is free walking at my home!!! :> It was taken during some free minuts (as you know, there are not too many during work...). I was talking with my colleague about our students and what to do to pay their attention on Blattodea (some of my students have serious problems with identification of cockroach species presented during lectures - they can not find differences between Blattodea and Coleoptera). After a few minuts of our conversation the new idea was appeared! And... here is the result :>

This is a female of American cockroach -Periplaneta americana (Blattodea: Blattellidae). As I noted above it was taken from our laboratory :>

Distribution: described from southern part of Unated States, even if probably native to Africa; presently - thanks to human activity - almost cosmopolitan

Habitat: hauses, restaurants, garners, ect.

Size: up to 4-4.5cm

Food: feeds on decaying organic matter and a variety of other foods

Running speed really fast - even 5.4 kilometres per hour, what is about 50 body lengths per second!!!

Life cycle: females produce egg cases and carry them protruding from the tip of the abdomen for about 2 days. Egg cases are then generally placed on a surface in a hidden location. Larvae emerge from egg cases in 6 to 8 weeks and require 6 to 12 months to mature. Adults can live even one year.

So my Friends, once again bon appetit and have you a very nice day! :>

Hello Radomir,
Funny picture! I hate these insects and I never would have suspected that you have these creatures in your plate:-). I think it's an excellent idea to present them to us. And as usual your picture is well taken.
Bon appétit quand même!
Kind regards

Siemanko Radku!
Bardzo ciekawie i dobrze pokazany niezbyt lubiany owad .
Gdzie Ty sie chlopie stolujesz :-).
Pozdrawiam Slawek.
PS. ten owad z dedykacja dla Ciebie to faktycznie cio³ek matowy.

a clever way to catch student's attention!

The photo would improve, if the exposure was measured on the cockroach instead of the fork i.e. the light on the animal; it would show more details of the roach...

Ehuehue:) A very different subject from you MF Radek. But an insect:> which also a biochorical agent (like vectors) of some parasitic diseases, such as an dysenterical amoeba Entamoeba histolytica cysts which can be found in sewers.. ighhh:>
Perfect presentation MF!
TFS this and have a nice WE!

Hello Radomir,
Very funny, but informative!
Good macro of a type that is not really encouraged on TN, as you know, but IMHO it is a useful contribution and this Periplanata is well shown with fine detail.
When I was in school many years ago both Periplanata americana and Blatta orientalis were used for dissection. Cockroaches have also come up in our news as they appear in badly maintained flats that are neglected by the local councils.
Thanks and have nice weekend,

I hate cockroaches, Radomir.
But this shot is superb, very well composed/timed.

Hello Radomir !
Wow, I just got up and was about to eat my breakfast, but I guess I'm not so hungry anymore, now ! :-) This is undoubtedly an unusual picture here on TN, but I love it ! So funny and disgusting in the same tim ! You really managed to bring out awesome details on the insect, and I also like the composition of the shot, and the fact that you have also included the fork. Exposure was well-managed. Very well done !

Hi Radomir,
a good joke, including the title alluding to Julia Childs! When we were living in Texas we used to have those big and ugly smelling Periplaneta americana at home in the kitchen. The "exterminator" had to come to bring relief. Alors, bon appétit mon ami!

Hello Radomir,
A fine view of a Cockroach that apparently is becoming more common in Sweden!! I had a huge Cockroach in my bed once in Delhi, but luckily I'm not that scared of insects although this species is not very pleasant!! I've seen some tiny ones in Gambia too and would certainly not be able to distinguish the different species.
TFS and best wishes, Ulla

Czesc Radziu
Tak jak Ci mowilem ta fotka jest super. Straszna i zabawana zarazem ;-) Pomysl z widelcem i resztkami jedzenia bardzo mi sie podoba ;-)

crazy idea! nice capture!

Hi Radomir

The running speed explains the difficulties on has to destroy them. I hope my murderous instincts do no upset you :-)
