Where is Spinochordodes Tellinii found?
The parasitic Nematomorph hairworm, Spinochordodes tellinii (Camerano) develops inside the terrestrial grasshopper, Meconema thalassinum (De Geer) (Orthoptera: Tettigoniidae), changing the insect’s responses to water.
How does Spinochordodes Tellinii control its host?
Spinochordodes tellinii is a parasitic nematomorph hairworm whose larvae develop in grasshoppers and crickets. This parasite is able to influence its host’s behavior: once the parasite is grown, it causes its grasshopper host to jump into water, where the grasshopper will likely drown.
Do grasshoppers have worms?
Two unusual, very long ‘worms’ that are occasionally encountered are horsehair worms and the nematode parasite of grasshoppers, Mermis nigrescens. Both are harmless to humans but may attract attention and cause concern.
Why do insects drown themselves?
Insects breathe through holes in the sides of their bodies. If they can’t get air in through the holes, they will suffocate. That’s why insects that are not specialized for living in water will die in water.
What is a tiny black worm?
Drain fly larvae are black and may resemble very small worms. They can come out of your drain or live on your shower surface. The drain fly likes moist conditions and lives in standing water. This makes the standing water in your u-trap piping a common place for drain flies.
Do cockroaches have worms?
Roundworm: Parasites such as pinworms and roundworms can travel on cockroaches and can be severely dangerous. Tapeworms: These parasites can cause serious illness and digestion problems. Dysentery: This disease comes from ingesting fecal matter, something that cockroaches do often.
Is a grasshopper harmful to humans?
Grasshoppers don’t usually bite people. But some types that gather in large swarms may bite when swarming. Other types of grasshoppers may bite people if they feel threatened. Grasshoppers aren’t poisonous, and their bites aren’t dangerous to people.

How are the larvae of a spinochordode ingested?
The microscopic larvae are ingested by their insect hosts and develop inside them into worms that can be three to four times longer than the host. The precise molecular mechanism underlying the modification of the host’s behaviour is not yet known.
How does the tellinii worm influence its host?
S. tellinii does not influence its host to actively seek water over large distances, but only when it is already close to water. The microscopic larvae are ingested by their insect hosts and develop inside them into worms that can be three to four times longer than the host.
