I run across so many insect bloopers and taxonomy fails I thought I’d start a little running feature on them to go with my ever enlarging file of Things That Are Not Fire Ants. I’m thinking monthly? Biweekly? Whenever I feel like it? We’ll see.
Anyway, today’s little gem is brought to you by Aspect Home & Pest, who really ought to know better. I present to you:
“Ticks”
“But wait!” you say. “Those are ticks. They are eight-legged dorsoventrally flattened blood-sucking arachnids.”
Yes. Yes, they are.
But keep on scrolling down the page. I present to you:
“Fleas”
“Um,” you say. “Those are still ticks. Fleas are six-legged laterally flattened blood-sucking insects.”
That is also true.
Whoooops.

The page you link to also has. . .
An African weaver ant (Oecophylla longinoda) called a harvester ant (Pogonomyrmex sp., noted as especially common in Arizona)
A Camponotus carpenter ant as a fire ant (Solenopsis). wrong subfamily. . .
And a Formica ant as an Argentine ant (Linepithema) – again, not even in the right subfamily.
Nice.
