Are wings found in insects and chelicerates?
Yes, wings are found in insects, but not in chelicerates such as spiders and scorpions. Chelicerates have evolved a different body plan that does not include wings for flight.

What is two chelicerates?
Chelicerates are a subphylum of arthropods that include creatures such as spiders and scorpions. They are characterized by the presence of chelicerae, which are specialized mouthparts used for feeding. Other notable features include their segmented bodies, typically divided into two main parts: the cephalothorax and abdomen, and the absence of antennae. Other examples of chelicerates include horseshoe crabs and ticks.
Which arthropods do not have antennae?
All arthropods apart from most insects have wings.
Which group of arthropods lack jaws?
Chelicerates (crabs, Pycnogonida, and Mercostonata) are arthropods that lack jaws.
What structures of chelicerates are analogous to the antennae of chilopods and other mandibulates?
A chelicerate does not have antennae because it is missing the nerve bundle that would control that structure. Instead, chelicerates use setae to detect changes in air currents and provide equivalents to smell and taste.
Why are horseshoe crab a arachnid?
They are not. Horseshoe crabs are chelicerates, a group that also includes arachnids, but they are in a separate class within that group.
