Legend
- The first three images show a normal engorged male Dermacentor andersoni on the left, a normal engorged female on the right and an engorged gynandromorph in the middle.
- The fourth image is of a newly moulted Amblyomma hebraeum female.
- The fifth image shows an engorged Amblyomma hebraeum female laying eggs. The three dorsal white “stripes” are Malpighian tubules packed with white crystals of the nitrogenous waste product, guanine.
- The last image is of an engorged Amblyomma hebraeum female showing the superficial appearance of a conjoined twin. The effect is likely due to an anomaly in cuticular expansion in the posterior of the tick rather than to an embryonic defect.
