Sphex pensylvanicus is a large, black wasp, significantly larger than their congener Sphex ichneumoneus (the great golden digger wasp). [6] Males are smaller than females, at only 19–28 mm (0.7–1.1 in) long compared with typical female sizes of 25–34 mm (1.0–1.3 in). [2]
The largest social wasp is the Asian giant hornet, at up to 5 centimetres (2.0 in) in length. [11] The various tarantula hawk wasps are of a similar size [12] and can overpower a spider many times its own weight, and move it to its burrow, with a sting that is excruciatingly painful to humans. [13]

The parasitism pressure exerted by ichneumonids can be tremendous, and they are often one of the major regulators of invertebrate populations. [ 20 ] [ 21 ] It is quite common for 10-20% or more of a host's population to be parasitised (though reported parasitism rates often include non-ichneumonid parasitoids).
