Homework Hotline: Millipede and Madagascar Hissing Cockroach


(CRAIG) ALL RIGHT AND NOW WOULD LIKE TO WELCOME TIM FROM THE ROCHESTER MUSEUM AND SCIENCE CENTER TO THE
SHOW HEY TIM. (TIM) HI GUYS. (DONNA) HI TIM. (TIM) GOOD TO SEE YOU AGAIN.(DONNA) BEFORE YOU TOUCH THOSE THINGS. (TIM) YEAH I WASHED MY HANDS. (CRAIG) SO YOU GOT HISSING COCKROACHES. WHERE ARE THOSE THINGS FOUND? BESIDES ON THAT LOG. (TIM) MADAGASCAR. (CRAIG) ALRIGHT. (TIM) THAT’S WHY THEY’RE CALLED MADAGASCAR HISSING COCKROACHES AND THAT IS ON
THE EASTERN OFF THE EASTERN COAST OF AFRICA. SO THEY’RE PRETTY
NEAT AND THEY’RE. (DONNA) OH I HEARD THAT. (CRAIG) YUPP YOU CAN HEAR IT. (DONNA) THAT’S WEIRD. (TIM) HISSING. THEY ACTUALLY HISS BY PUSHING AIR THROUGH THE SEGMENTS IN THEIR ABDOMEN. WHERE THEY
BREATH THROUGH. SO THEY’RE THE ONLY INSECTS THAT REALLY
DO THAT. YOU GET OTHER INSECTS THAT MAKE NOISE USUALLY THROUGH
SOMETHING LIKE STRANGULATION OR RUBBING BODY PARTS GATHER. HE DOES IT AND HE’S GOT THREE DIFFERENT ONES. THAT ONE WAS
BECAUSE HE WAS STARTLED. THEN HE’S GOT ONE FOR MATING. TRYING TO ENTICE THE FEMALES AND THEN ONE FOR FIGHTING. WHEN HE’S GOING UP AGAINST ANOTHER MALE FOR
DOMINANCE. (DONNA) NOW HE’S PRETTY BIG. HOW LARGE WILL THEY GROW AND
HOW LONG IS A TYPICAL LIFESPAN? (TIM) ACTUALLY HE’S SMALL COMPARED TO THE FEMALE. IF WE TAKE A LOOK AT
THE FEMALE HE’S ABOUT, HE’S JUST UNDER THREE INCHES. THE FEMALE
WILL GROW TO ABOUT THREE INCHES LONG. THE MALE BE TWO TO THREE
INCHES AND YOU CAN TELL THE DIFFERENCE BECAUSE THE FEMALE THE CROWN DOESN’T HAVE ANY HORNS
AND THE MALE DOES. (DONNA) OKAY YEAH I SEE THAT. (CRAIG) SO WHAT DOES THEIR DIET
CONSIST OF? WHAT ARE THESE GUYS GONNA EAT? (TIM) THESE GUYS EAT JUST ABOUT
ANYTHING. THEY LIKE THINGS, THESE GUYS EAT DOG FOOD. FOR THE PROTEIN BUT THEY CAN
LIVE ON VEGETATION JUST LIKE ANY OTHER INSECT ROACH THAT GOES AROUND. THEY’LL CHEW ON ANYTHING THAT’S ON THE GROUND. SOMETIMES
EVERY NOW AND AGAIN A LITTLE CEREAL OAT CEREAL THEY’RE LIKE YOU
KNOW JUST CHANGE PACE. SO THEY ENJOY THAT AND THEY DO PRETTY WELL WITH IT. (DONNA) ALL RIGHT NOW YOU TALKED ABOUT THE HORNS BUT ARE THESE THINGS
STICKING OUT ANTENNAS? (TIM) THOSE ARE ANTENNAS. THOSE ARE THE ANTENNAS AND THE FEMALES HAVE A LITTLE BIT LONGER THAN
THE MALE. THIS ONE HE’S LOST. HE MIGHT A LOST ONE IN THE FIGHT. AND BECAUSE HE WAS IN WITH OTHER
ONES AND SO HE TURNED AROUND WHEN I WAS ACTUALLY PICKING A
ROACH I WAS PICKING THEM UP TO SEE WHO WOULD HISS AND HE HISSED THE MOST SO I’M FIGURING HE PROBABLY THE DOMINANT ONE. (CRAIG) RIGHT. (TIM) MAYBE HAD A
LITTLE FIGHT GOING ON. (CRAIG) RIGHT SO YOU’VE TALKED ABOUT THESE
GUYS MAKING NOISES. WHAT OTHER KINDS OF INSECTS ARE GOING TO
MAKE SOME NOISES AS WELL? (TIM) WELL YOU GET YOU GET CRICKETS THAT’LL MAKE NOISES. (CRAIG) AND THAT’S RUBBING THEIR HIND LEGS TOGETHER. (TIM) THE CICADAS THEY MAKE NOISES. SO THEY
THERE’S A LOT OF DIFFERENT ONES BUT ONLY THESE HISSING
COCKROACHES ARE SOME TWENTY SPECIES OF HISSING COCKROACHES
ON MADAGASCAR. SO THEY ACTUALLY
MAKE THAT SAME NOISE. (TIM) NOW YOU ALSO BROUGHT
ANOTHER. (TIM) I DID. (DONNA) IS IT AN INSECT OR SOMETHING FOR US TO SEE. (TIM) HE’S A POD. HOLD ON. (DONNA) HE’S A POD. HE’S A TOUGHY TO GET A HOLD OF. (DONNA) NOW THESE GUYS WON’T GET OUT WITHOUT THE LID ON WILL THEY? (TIM) NO. THEY WONT GO FAR. LET ME SEE IF I CAN FIND HIM. HOLD ON. THERE WE GO. (CRAIG) HE’S GOT A NECKLACE. (DONNA) AWW HE’S GOT A NECKLACE ON. (TIM) WELL IT’S MARDI GRAS. (CRAIG) AH MARDI GRAS. (DONNA) WHAT CREATURE IS THIS AND WHERE CAN WE FIND IT. (TIM) THIS IS OUR MILLIPEDE. OOPS GOT IT ON THE BACK END. THAT’S ALRIGHT. BUT THAT’S ALRIGHT. I WON’T TELL YOU HOW IT GOT THE BEADS BUT THE KICK LINE IN THE CONGA WAS TO DIE FOR. BUT THIS IS THAT OTHER INSECT. IT’S WELL NOT AN INSECT. IT’S A POD. IT’S GOT.. IT’S A MILLIPEDE IT DOESN’T HAVE
A THOUSAND LEGS. IT’S ONLY GOT ABOUT FOUR HUNDRED. AND BUT HE’S REALLY PRETTY COOL
THEY’RE THEY’RE ACTUALLY ONE OF THE FIRST TO COME OUT OF THE
OCEAN. DURING ABOUT FOUR
HUNDRED AND FIFTY MILLION YEARS AGO SO FIRST TO TAKE THE LAND
WHERE THE MILLIPEDES AND CENTIPEDES. (CRAIG) WHAT CHARACTERIZES THIS AS A POD COMPARED TO AN INSECT? (TIM) THE NUMBER OF LEGS. (CRAIG) SO INSECTS HAVE SIX. (TIM) SIX AND THE NUMBER OF BODY PARTS BECAUSE HE’S GOT SEVERAL SENTIMENTS AND IF YOU NOTICE IF
WE CAN GET A GOOD LOOK AT HIM OR HOLD HIM YOU CAN SEE THE THE LEGS MOVE. (DONNA) HOW THEY MOVE YEAH. (TIM) THE FIRST FEW SEGMENTS WILL HAVE ONLY TWO LEGS ON EACH SECTION
AND THEN FROM FIVE BACK THEY’LL HAVE FOUR LEGS ON EACH SECTION.
(CRAIG) INTERESTING (TIM) AND GO AHEAD. (DONNA) HOW
LARGE IS HE GOING TO GET? (TIM) THIS ABOUT AS BIG AS HE’LL GET. SIX
MAYBE SEVEN INCHES. HE’S NORTH AMERICAN SO HE’S
YOUR FIND, CRAIG YOU SAID YOU FOUND SOME. (CRAIG) OH WE WERE IN LETCHWORTH WITH THE BOY SCOUTS AND THE GUY HAD ONE A LITTLE BIT SHORTER THAN
THAT BUT IT WAS ABOUT AS BIG AROUND AS THAT ONE. (TIM) WELL SAME KIND OF LOOK TO IT SO YOU FIND THEM ALL OVER BUT MOSTLY THEY’RE
TROPICAL THEY BECAUSE WELL AS MOST INSECTS OR MOST
PODS LIKE THIS THEY’LL LIVE BETTER IN TROPICS, WARM WEATHER. SAME WAY WITH THE ROACHES. THE
ROACHES WILL DIE IN COLD WEATHER BECAUSE IT WON’T BE ABLE
TO BREATH. (CRAIG) OKAY. (DONNA) NOW DOES THE MILLIPEDE HAVE ANY DEFENSE MECHANISMS? YOU TALKED ABOUT THE HISSING FOR THE
COCKROACHES. (TIM) AS A MATTER OF FACT IT DOES. IF YOU COULD SEE ON THE ENDS OF
MY FINGERS YOU’LL SEE THE
LITTLE YELLOW AND HAVE THEY SECRETE FROM THEIR SEGMENTS. AND
IT’S USUALLY SOME KIND OF A TOXIN FOR HUMANS IT’S NOT
ANYTHING MORE THAN IT DISCOLORS THE SKIN. (CRAIG) WE KNOW FIRST AID
SO. (TIM) BUT YEAH SO I’M I’M GOOD TO GO I’M SURE. BUT FOR OTHER
INSECTS IT’S A TASTE SOME OF THEM HAVE SOME MILLIPEDES HAVE REALLY TOUGH TOXIN SO AS SO AS THEY A TASTE IT ITS A NEURO TOXIN. THEY’LL STOP BITING IT AND THEN BUT IT ALSO THESE GUYS
ROLL UP INTO A BALL TO TRY TO PROTECT THEIR LEGS AS THEY GO
ALONG AS WELL. (DONNA) WELL TIM I WOULD
