Lycaenidae - Wikipedia
网页Many species also have a spot at the base of the tail and some turn around upon landing to confuse potential predators from recognizing the true head orientation. This causes predators to approach from the true head end resulting in early visual detection or to attack the false head ending up with a beak of dusty scales.

网页Common Name: Blues, Coppers, and Hairstreaks. Description: Lycaenids are small, delicate butterflies that are often distinctively marked with iridescent blue, red, or orange. Hairstreaks usually have wispy tail filaments at the back of their hind wings.
False head complexity and evidence of predator attacks in male …
网页2019年6月25日 · The “false head” of Lycaenidae is considered an adaptation for deflecting predator attacks to less vulnerable areas of the animal. Robbins (1980) found that the complexity of FHs is positively associated with the proportion of specimens with symmetrical damage in the FH area, a likely evidence of failed predator attacks ( Van Someren, 1922 ).
A Review of False Heads in Lycaenid Butterflies - ResearchGate
网页2022年5月24日 · False heads are predominantly found in the butterfly family Lycaenidae, especially the hairstreak subfamily Theclinae where the false head is found at the posterior margin of the hindwing....

网页2020年6月29日 · Along this spectrum of interactions, lycaenid caterpillars have evolved specialized morphological features such as a thick cuticular dermis that protects them from ant aggression 19, extended...
An example of a lycaenid butterfly with "false head" depicted …
网页In many butterfly species of the family Lycaenidae, the morphology and color pattern of the hind wings, together with certain behaviors, suggests the presence of a false head (FH) at the...
Two heads are better than one: false head allows Calycopis …
网页The deflection of attack from vital organs to the wing margin is regarded as an important adaptation in hairstreak butterflies. However, this “lose-little-to-save-much” strategy akin to the detachable lizard's tail had never been tested experimentally. The present study tests the “false head” hypothesis by exposing a hairstreak ...
网页An even more striking apparent deflective adaptation is the so-called “false head” coloration found in the diverse butterfly subfamily Theclinae (Lycaenidae) (Cordero 2001; Robbins 1980), which...
The Lycaenid "false head" hypothesis: historical review and ...
网页A fascinating proposed example of protective coloration is the hypothesis that the wing pattern and behavior of lycaenid butterflies (Lycaenidae) create the impression of a head at the posterior end of the insect, thus deceiving predators into attacking the less vulnerable end of the butterfly.
Lycaenidae - an overview | ScienceDirect Topics
网页The head is broader than the thorax, with the antennae widely separated and enlarged distally into a club with its tip (apiculus) attenuated and curved. The flagellum is strongly bent at the club in Pyrrhopyginae. The proboscis is well developed, and nearly all species feed at flowers, bird droppings, or other nutrient sources.
