Mader (2010) conjectured that for any tree T of order m, every k-connected graph G with minimum degree at least⌊ 3 k 2⌋+ m− 1 contains a subtree T′≅ T such that G− V (T′) is k-connected. A caterpillar is a tree in which a single path is incident to every edge. The conjecture has been proved when k= 1 and for some special caterpillars when k= 2. A spider is a tree with at most one vertex with degree more than 2. In this paper, we confirm the conjecture for all caterpillars and spiders when k= 2.
