Skovdjævle, skjoldbærer eller skovtrold. Bøgespinderens larve har mange navne og ikke uden grund. Den ser så fremmedartet ud at den ikke forveksles med andre.
Super camouflage. Bøgespinderen (Stauropus fagi) er egentlig en lidt uanselig natsommerfugl som de færreste ser. Når den sidder på bark falder den utrolig godt i med omgivelserne og er derfor meget svær at få øje på. Larven derimod er en helt anden historie. Her er formålet ikke at falde i med omgivelserne, men at afskrække fjenderne med et frygtindgydende udseende. Larven kaldes også for skovdjævlen, hvilket er forståeligt, når man ser larven. Larvens fremmedartede udseende får mange fjender til at holde sig væk og den kan endda løfte bagenden når den bliver truet for at se endnu mere frygtindgydende ud.

Fakta om bøgespinderen:
Den voksne sommerfugl har et vingefang på 40-70 mm.
Den er grå med grønlige og brune nuancer.
Larven kan blive op til 70 mm lang.
Larven er lysbrun til rødbrun i farven.
Den voksne sommerfugl ses fra omkring maj til juli, men larven ses fra sidst i juli og til september.
Larven spinder sig ind i visne blade og overvintre som puppe.
Bøgespinderen tilhører tandspinderfamilien.

At Bøgespinder-larven ikke kun kaldes skovdjævel, men også for skovtrold, langbenet skjoldbærer og korsfodet skjoldbærer?
At larven lever oppe i toppen af særligt bøgetræer, men også på eg, birk og hassel?
At arten er almindelig i Danmark i løvskove?
At det er hannerne som finder hunnerne ved hjælp af lugtesansen når de skal formere sig?
At larvens første og eneste måltid i den første uge er den æggeskal som den kommer ud af? Den spiser ikke andre larvers skal, men dør hvis den ikke kan spise sin egen.
